The community I've ever been is actually very nice, but the majority of the community, especially the fanfic one might be toxic, according to a lot of users.
Spam and troll exist, and so plagiarist and copyists. You can get the account and works to be taken down by reporting them, or for direct result, contact the ambassador (of the corresponding country and language). They works well and kind enough.
I haven't been here for some time but I still believe that BL, fanfic (of popular things), and romance is still popular.
Growing on wattpad is slow, except you enter the right fanfic community.
So far I'm pretty much good with wattpad bit maybe I'm just in the right community. I also lurking on the ambassador page a lot too in the past, to see information of some very troublesome troll and toxic users that git reported. OwO
