Where did I wrote that?

Posting in a thread is not the same as relying on the auto watch function:
I would assume most regular users, especially those who post a lot, have the second option unchecked.
Again, unwatch is not a thing if you didn't set it on watch in the first place (auto watch counts as that) and it won't help you in any form to sort out game threads you already checked out.
F.95.zone has a limit on how many threads you can set on ignore, 1000 is the maximum. So this is pointless.
I explain why they do that, not to justify it. And why is a THX more useless and clutter more than any other "Thank you" posts that's done with more words?
