Lost xp for not even spamming..

I read all the threads and answered them as correct as possible

You can lose XP if the thread itself was removed (the spam thread), you just don't lose 10XP, you lose 1XP.

So that's 1 xp, when you post a comment ? I've been wondering that for quite some time, but never found or got any answer.

EDIT : Also, yeah, I lost xp like that as well when I started to talk in the forum. I still have no idea what were the threads I commented on that could have been considered as spam, I guess I just wasn't paying much attention yet, but in any case, now that I stopped leaving comments on spam threads like that, I've never lost xp again (meaning "for the last 2-3 weeks or so" I guess. Whatever, few weeks rather than months are even years is accurate enough).

Oh, thanks for the info @pavel_hristov,
guess it's best to avoid spam threads

Why it always

You can't comment that often
