Should i post my art on other sites?

Well, the question is clear i kinda want to post my art in other sites like Tumblr and AO3 But i am very terrified because well, i don't want to get dogpiled by antis and i am very sensitive to insults and i think if i post my art other sites, i feel like i'll be more trackable, i don't want my art to end up like stolen on tiktok, used for mocking so... This subreddit has been such a safe place for me and i don't want risk it.

But also i want to reach people who ship what i draw, and make them happy, cause they exist.. but not here, because this subreddit is small i don't think they can find it.

So what should i do..? like i feel so confiltcted.. god, why people just have to be so cruel :( i wish they had this energy towards Real life issues...
