rule 34
Rule Thirty-Four (r34 or rule34) refers to a "rule of the internet" that "if it exists, there's porn of it. No exceptions"
This is not true 100% all of the time, thus the birth of r35. "if there is no porn of it, it will be made."
Even though in theory by definition this should be applied to ALL porn, in practice it is used only for things with non-pornographic origins. Paheal, for example, bans uploads for things like "La Blue Girl" because it was already porn to begin with, so "there's porn of it" is quite superfluous.
Another requirement some instate is that it should only apply to major/established franchises, so that it doesn't get spammed for OC characters made up on the fly.
The lines can get blurred with these concepts depending on popularity. Some webcomics for example may start out as being classified "OC" but as they gain popularity, become recognized as "established" where erotica drawn of them gets considered to be 34.
It's more obviously 34 in cases like where it's had a TV series or anime made about it, since that is high-budget. In terms of manga or comics this can be tougher to determine, since it might need to depend on how much something was purchased/circulated.
About the rule34 paheal and its purges of loli content.

https://rule34.paheal.net/
Rule34 paheal was created in early 2007 and has become the pinnacle of drawn porn of all kinds from loli/shota/cub to hentai and furry. for years this was the perfect website for all drawn porn.
as the years went on the owner of the website wiiaboo started posting announcements in early 2010 about removing toddlerkon and questioning the removal of lolicon/shotacon. Toddlerkon to this day is still banned and will likely stay banned. by early 2012 all relistic 3D loli/shota was banned. In late 2013 more announcement regarding the laws over in the the UK and europe and the possibility of loli/shota being removed due to these associations (alleged) pushing to have the content removed.
in june 2015 the great loli purge happened wiping out many tags and artist including a few major artist like g_reaper and Incognitymous and much more. not all loli was removed only certain tags were hit like Mabel Pines, Vanellope von Schweetz, and Lilo and Stitch, and Toy Story, for example. shota wasnt effected much in this purge for unknown reasons. after this event the beginning of unannounced loli/shota purges started.
Ever since then random tags, posts, and artist, have been deleted without any warning.
Examples: Chloe_Park, maximilo, LazyTown, destijl, conoghi, Dora_the_Explorer, Riley_Anderson, and LazyTown.
Over the years a message intermittently would be displayed in red on the site stating to "Please continue to find and report images that break our rules on "underage content"." which inevitably something would be wiped out each time this message was displayed.
Despite all this, cub is still allowed and was never effected. Since the purge of loli, posts that were deleted have been restored to some degree and tons of loli can still be found on the site. by late 2020 a zero tolerance announcement was put in to place for loli/shota, but weather they do a full site purge has yet to be seen and is unknown if it will ever happen.
These events lead to websites being created to migrate away from rule34 paheal.
including but not limited too: baraag, atfbooru, etc.
before these site existed most content got migrated to exhentai multporn and rule34hentai.
