I’ve just checked through your profile and posts, and I can’t understand your problem. Your involvement on the site is fairly low, and mostly many months old. Do you have more than one site name, with aggression to another name? Is someone being aggressive to you? About what? Do you want someone else being blocked just to you (Bellerose63)? Or to everyone?
We have been asking for that feature and the Admin says they are working on it. But till then, we can't block someone responding to our thread. We will never be able to block someone from someone else's thread. That will be up to the OP.
What’s it all about, Alfie?
