You can edit your post after you post it to by pass the character limit.

I also highly suggest removing swears in your post, as GMs might suspend you for that.

There is already a very sizeable thread dedicated to horror stories from the Duty Finder.

And lastly, I'm sorry this happened to you. You can absolutely report them even though it's not RMT, In the menu with the log out function and whatnot, there's a place to contact a GM to report harassment. There might be a chance the GM will shrug it off for "different playstyles", but you won't know unless you try.

(edit) Wow you all type fast. Made all my points before I posted. D:
