To clear some (possible) confusion on my data
There's a bug with code-tags in my script (instead of removing the quote, it shows what's inside the code-tags). I've tested it by quoting the same post again: when I quote the post without adding anything, I get the exact same data. That makes me believe this post was an exact quote.

As far as I know, only Admins can see deleted posts.

Quote

This would clearly demonstrate how much time has passed between the Phetis' post with BTC address and Xal0lex' quote, and when Xal0lex exactly has removed his message.

I can narrow down the posting time: Post 48584270 was created between posts 48584269 and 48584271. That gives a 10 second window (83 to 93 seconds after Phetis' post).
I don't know when it was deleted.

Especially in the Stake address thread, deleting posts can be damaging if a user ever needs that quote. You've quoted posts before (here and here), which you didn't delete.

Freedom of speech
I remember theymos saying he'd rather have someone create an alt account if he's afraid to share his opinion for whatever reason, than not posting it at all. This was quite a while ago, so I can't easily find back the quote.
