...Looks like this guy is one of Yobit sig participant who spams on this forum and he got banned. No need to reply to them, dude. It's a waste of time.
Thanks for this suggestion.
To be honest I didn't know what to do or how to behave in relation to these posts because they are little spammy but looks like authors know the subject but hasn't read the OP correctly.
First I wanted to report them but later I thought "maybe I am wrong" and to be a cultural leader of the discussion tried to answer this questions, by the way, noting inappropriate behavior (unread OP).
But you are right this is spam and should be reported, skipped or simply ignored. Like in my personal text SPAM = IGNORE and should stick to this.
