Wow, so we can check where and when we get it, can u give me link archive site that archives this forum regularly?
https://archive.org/ used to do it daily I think. They've stepped it down from then but there's still quite a few archives of the site (it's done at least once a week at least - normally more).
Whether the thread be trashed or the post deleted, it simply means that the post does not contribute to a discussion. This may not be the case for all posts but should encompass most deleted posts.
No.
The OP can delete a post. Say I open up a topic to complain about someone here, every response I get says that I'm wrong and some of those posts get merited. Then, enraged by everyone's narrowmindedness, I delete the thread - it doesn't mean their posts weren't worth meriting. This means that someone could attack some people who post on threads. Also, who do these merits then go to? Do they go back to the sMerit spender or do they just disappear.
If the thread gets deleted by a mod then obviously, that's a completely different story...
