Are deactivated players on QLStats known cheaters?

If so would it be possible to get a list of all their Steams ID`s in one text file so as to add them to my server access list? This would save a lot of time trying to weed these players out.

Thanks in advance


PS any such list would have to be corroborated by public inspection so as to avoid any innocent players being added erroneously or even maliciously.
