It is going to cause overhead on the forum software to do that I guess. However, censorship like that is bound to cause issues. I would love nothing more than ToxicBunny not being able to read a thing I post here, but I've learnt that putting he/she/it on ignore is the best I can do and it works. I don't have to see his snarky personal attacks and it appears others also don't see it or care
I can selectively read his post or not, but he definitely doesn't has the right to read my post.
if he is still responding my post but I can't read, he can keep doing personal attack against me but I can't respond. I feel like I am an ostrich.
