I've been harrassed a few times, including DMs on at least three occasions, (and even one person who continued to harrass me in DMs on the main site when banned from the forums), but not so much recently. Since the discord started up, a lot of the people who just want to rant have moved over there instead, and the mods here have generally been good at tackling this stuff.
There has historically been a bit of an issue, which I've heard many times from different people, with the forums being a bit hostile towards people with larger subscriber counts (and not even that big in the grand scheme of things, like over 500 subs), especially if they happen to be LGBTQ+ and create content themed in LGBTQ+, BL or GL. It's why you don't see a lot of people with larger sub counts here. There's often a bitterness towards people who have managed to build a larger audience on the platform rather than an eagerness to learn how they did it or to try to replicate their success through emulating their methods.
It does seem to be better these days, but the reputation still lives on, sadly. I mostly post here just to try to help other people out 'cause I like doing it, and if I want to talk to people about relateable problems being in that annoying middle zone of a few thousand subs, I go to private discords because so few people around that level feel comfortable posting here. It's a shame though, because when I was a newbie, hanging out on places like the Sweatdrop forums, where I could get advice from people a bit further along in their comics development with professional experience, or success in doing the things I wanted to do in a casual, accessible way was so useful to me.
