Current 4chan fat thread:
 
http://boards.4chan.org/mlp/thread/23278259
 
Including the link to this pastebin and/or linking to a prior thread in the OP makes my already easy job even easier, and is appreciated.  I'll get around to updating that shit someday, probably in another year or five.
 
Scruffy may nuke the thread if he's having a bad day.
 
For previous and possibly current 4chan threads refer to:

http://pastebin.com/u/Inkwell
Pones are fairly in character, descriptions of chub are plentiful and detailed, weight gain is progressive.

http://pastebin.com/u/Bother
Focuses a bit more on background horses, has a series called Embodiement featuring anthro pregpon.  Great descriptions and very boner-worthy, excellent if you like belly rubs and outie belly buttons.  May be ded, but keeps coming back.
 
http://pastebin.com/u/tubbyspikey
Home of the author of "Tubby-Wubby-Spikey-Wikey," which obviously features a fat Spike.  Good if you're into that sort of thing.  Seems to be pretty dead, but there's always a spikefag somewhere.

Fat pone is found in the Spectrum series.  Part 1 is the prologue, with 2 featuring Twilight, 3 Pinkie Pie and 4 Applejack.  Also check out "The Stuffenating," which contains Pinkie Pie/Fat Rainbow Dash.  Includes other fetish stuff too, usually of the (very) gay penis persuasion.
 
http://pastebin.com/u/StingingScratch
The same guy that did Massive Mrs Cake came back and did a Spitfire thing.  Has gassy pony in it, but you might be able to look past that.

http://pastebin.com/SxsxkFUG

Block dem fukken advertisments (only moral/redditfags donate)
Scald eyes when fat tag brings up large hairy men
With an account, go through all preferred fetish tags, favorite anything you would fap to, and escape Sturgeon's Law.
Upload ponybutts that you've seen/saved but aren't on there, with regards to the DNP artist list
 
 
 
4) Tumblr pones
 
I still have no fucking idea how to navigate Tumblr
 
http://rdisbestchub.tumblr.com/
Cutesy chubby adventures of Speedyfast as she eats things and gets bigger.
 
http://trinityfate62.tumblr.com/
God-tier shading, will possibly make nsfw-type stuff.  
 
http://dufelbagofdraws.tumblr.com/
Clean lineart and pretty good coloring jobs, lots of anthro and Rarity.
Dufel occasionally streams at:
 
http://www.livestream.com/dufel
 
http://askchubbydiamond.tumblr.com/
Draws soft, squishy and occasionally bordering on blobby ponies.
 
http://redintravenous.tumblr.com/
probably ded in favor of that other blog
 
http://caloriescorner.tumblr.com/
 
http://the--pudgy-workshop.tumblr.com/
Lots of sketches.
 
http://overfedvenison.tumblr.com/
Envy's blog-type thing, general stuff but that's where the fat pone is occasionally posted
 
http://a-defenceless-pony.tumblr.com/
Contains rounder horses, see also defenceless's FA gallery.
Ded-ish
 
http://bright-spark-pony.tumblr.com/
Contains sketchy round horses, doesn't get much traffic
 
http://pondunkadunk.tumblr.com/
Contains lots and lots of butts
 
http://ask-banana.tumblr.com/
Contains round horses.  Ded
 
 
 
5) Furfag affinity/Deviantard galleries and shit
 
Given that these people could have stuff other than pone, you might as well search for them on Ponibooru unless you're curious/into that sort of thing
Note that you'll also need to make an account to see nudity
 
http://www.furaffinity.net/user/chloridecull/
Writefriend who's doing a fat pon text adventure - check twitter for updates I guess.  Written stuff is pretty good, focuses more on the size of the pony than dicks being stuffed into pony holes.  
 
http://trinity-fate62.deviantart.com/gallery/43620730
Big, round, soft and flabby ponies.  Occasionally noseless anthro.  Great coloring jobs and superior shading leads to pon looking even more pillow-like than most.
 
http://www.furaffinity.net/gallery/drumstickpony/
Draws round, possibly flabby pon, semi show accurate in terms of style.
 
http://pony-pudge.deviantart.com/
Pony Pudge's deviantart account.  Contains monochrome somewhat sketchy pon, requires a blood sacrifice of a couple cents for some DA points to spend, but takes suggestions for free.
 
http://www.furaffinity.net/user/sirmasterdufel/
Uses thinner lines, good at drawing pudge and jiggling.  Some of you probably know him from his Rarity or Applejack sequences.
 
Dufel occasionally streams at http://www.livestream.com/dufel
Check the current 4chan thread (if there is one).
 
http://www.furaffinity.net/gallery/redribbon/
Big and cute pone abound.  Good at drawing squish.
 
http://www.furaffinity.net/gallery/calorie/
Resident artist from /mlp/.  Usually takes requests, half-way show accurate.
 
http://www.furaffinity.net/gallery/defenceless/
Good if you like expandy/bloaty pone, might have bonus appeal on top of fat pone due to situations and short stories.  Pones are usually fuzzy.  Ded ;_;7
 
http://www.furaffinity.net/gallery/fatpony/
Hit and miss, lots of GLORIOUS MOONBUTT and her GLORIOUS BUTT
Also bubblebutt Derpy for good measure
 
http://www.furaffinity.net/gallery/sagejackal/
The dead nor the living will ever know peace from this evil.  Go in for anthro pone pictures, get out as fast as possible.
Known as Revadiva or Revadiehard on Ponibooru
 
http://www.furaffinity.net/gallery/naughtyblush/
Pregnant grey and pink OC horse.  Only a few pictures.
 
http://eggo81194.deviantart.com/gallery/38100869
3DQT pone, kind of neat
Everything else is 3DPD
 
http://xniclord789x.deviantart.com/gallery/40761959
Pregnant pone.  Has other pregnant nonponies too (dirty casual 360nohooves).
 
 
 
6) If you want to give me links to things I missed, or something you want in here, be it pastes, galleries or trojans, or feedback in general you can send electronic mails to mootmakebangopls@yahoo.com
just kidding I forgot the password to that a while back
 
The most ideal way to get something to me is to post in the 4chan thread, though other sites listed here work too.
 
I'll continue updating the pastes and links as more content is found.  This is sort of a lie, for the most part I just fap to new things on Derpibooru and call it a day.
Apologies for any outdated or accurate descriptions, or dead links.
 
Happy fapping!
