Props to the person that made the chart though, given that fimfic probably has better tag usage than derpi, I’m sure this chart is fairly close in the fiction department.
 
Source:  
fim doesn’t have ship tags, so these numbers were from searching for character/character + romance and character tag filters. these numbers seem HUGE though?? i really don’t have a way to confirm if every story actually featured the ship but i have to assume so, maybe someone more familiar with fim can double check my search
 
I’m not sure exactly what method they used, but for the Fimfiction side of it, they may have included shipping stories where the searched-for characters were side characters to a different ship. They’ve also used FFN and ao3, but the numbers from there are rather low for duplicates to be much of a problem.
 
Plus - while uploaders are better at tagging their own works over there - we have mods, assistants and users adding and correcting tags here on Derpi.
 
Tags are serious business, yo.

That’s because it’s liked a lot by some artists, but not so much as a fandom whole  
@Background Pony #3C8C  
Because art doesn’t need to have a believable story to be appreciated. It’s much harder to believe the two can have a healthy relationship (read: they can’t, really :P) in a story without one or the other seeming OOC.
 
This postpretty much covers it. Also rarity x spike is by and far the most shipped pairing hands and hooves down. Selectively applying some arbitrary filter is just for attempts at making something “look” like a legitimize arguement.
 
Adding fiction and art together I was gonna say appledash might edge out, but having checked tags twidash seems to have had a resurgence in art lately. So discounting spike, it looks like twidash>appledash>flutterdash/rarijack with art and fiction.
 
Really these numbers are still misleading due to duplicates, mis/untagged and pieces that aren’t even posted to either site. and should minor edits be counted as separate pieces (not imo)?

Other shipping charts get upvotes, though.
 
I reckon it was because it was a pie chart without any indication of where the data came from or how they collected it. Source mentions several fanfic sites, but it could’ve been Derpibooru tags or made-up numbers for all the image tells us.
Background Pony #3C25
Oh this is percentages of ship content based on the site “fimfiction”.
 
 
It’s funny how disproportionate Rarijack fanfiction there is to fanart. Even on Derpibooru, Rarijack has the most images of any m6 pairing.
Background Pony #9C82
Rainbow Dash is most m6 lesbian-ed pony. Can’t say I’m shocked, but can’t say I saw the numbers going that way.
 
@Background Pony #3C8C  
This
 
 
@Background Pony #874F  
Probably this. There are also people who get mad when the m6 are portrayed as homosexual as well. “What?! Fluttercord/Cheesepie/Rarimac isn’t on this?! DOWNVOTED!”. Also the people who get peeved at shipping in general. Upvoting; for statistics and for chuckles.

what’s with all the downvotes?  
people are mad their OTP isn’t the biggest one?

Raritwi in the top 5? That surprised me.

Or one could randomly choose another set of pairings to ignore and say it’s, i dunno, flutterdash, twijack and raripie? That ‘top valid pairing’ is pretty irrelevant.

Going off the most popular and ignoring when a character is repeated that makes the top valid pairings:  
Twidash  
Rarijack  
Flutterpie
