2015 when they still allowed gif profile pics , I was both uploading and reading a lot of webcomics back then , so I was about 17? It was a good time, I was active in the forums, made a comic friend @Vikiro_Hop (he doesn't do comics anymore) the site design was better for creators and newbie comics too.
Then about 2 years after that I stopped engaging here, ALOT of people left (or seemed too) when changes were made to the site and also money incentives on webtoon (I think I don't know). I think everyone and a while I would upload a gag comic but that was infrequent since I was at uni at the time.
I think about 2 years after that I made another long-form story comic and got back into webcomics so I popped back on to tapas and followed a couple of stories here closely like @MissMagicGirl 's "Magic Advisor " comic, I think at that time there was a large amount of GL and BL comics too (still is but there was less 'manga' versions")
Then after two years I finished my 2nd long form story comic and left again, that's probably when the novels started to appear here and the ink thing started to be pushed.
The recently last year I started to post some more gag comics here but I was more focused on posting to reddit, I've given up on building an audience here a while ago.
I've been here since 2015 and still haven't gone past 100 subs (for a singular comic series) which makes sense since I'm not actively pushing my stuff here, I don't even engage with sub for sub because I feel that's disingenuous (you do you I ain't judging, but to me I would like people who read my comics not just pumped numbers)
Also since my friend had stopped making comics there was less of a reason to be here/make comics. So yeah all that combined with that a lot of the comics I used to read and follow also stopped being made I have been here at least since 2015 but not all those years I was here actively.
