Here you can block a user from sending you private messages. Unfortunately, there is no option to block a user in your topics. If someone bothers you about in your topic, press report post and move on. Each report is checked by the staff team.

If a person after blocking tries to bypass the block, for example by sending you fg and entering a comment there, report it to the moderator about the attempt to bypass the block

Use the report button.
If someone is harassing you via PM just block them.
