I don't think it defeats the purpose. Its an online forum, I actually like that PC doesn't allow for arguing, many "civil discussion " do turn into some not so nice interactions or people feeling picked on or ganged up on.... and thankfully trolls don't last long here.

If someone has put me on ignore, well they must have a reason , if I cant reply to a thread I basically am like .....meh... I move along.

It's all good. Whatever works for a person is what they need to do for themselves.
