@Vlk, it's not "nice" to delete valid posts that are respecting the forum's rules 
Why do you think it was Vlk who did anything with them? 
Although this is OT, I don't want to leave your question in the air.
Before
Vlk posted in this topic, there were a couple of spammers/trolls/trashers posting all over the forum, including in this topic.
I (and others) posted (in this topic and others) after one of those non-welcomed posts, yet before
Vlk.
I have reasons to believe that those trashing posts were deleted, together with some other
valid posts, including mine.
Not only
Vlk happened to post in this topic after my (deleted, not by me) post, but he is also the Global Moderator of the forum.
Whether, he in particular is the specific mod that deleted those
valid posts (mine was NOT the only one), or whether some other mod decided to "massively" delete posts (valid or otherwise), is not the *key* word/phrase in my previous post.
From my point of view, as a simple common forum member,
Vlk is still the main address to respectfully request to avoid this type of actions.
Let's close this OT, and hope this won't happen again.
