Is there any way to block someone that responded to my post and where the trade went to shit due to un-professional behaviour, so that when I post trades ISO or FT in the future, they can't access? Or in any way it is blocked so that I don't have interactions with them again?

You can only block via the PMs at this time, but there have been browser extensions for this. I'm not sure to what degree.

Great, thanks buddy!

you can only block PMs or instal addin that will hide the posts, but you cannot stop someone from viewing or respoding to your posts

Yeah I understood as much, thanks. Got into an entire shitshow earlier. So hoping I can prevent that with some traders now. There should be like a "rep" thing where people can upvote each other or something, maybe review each other. Donno. Anyway. Thanks guys!
