Fun fact #1: that person is likely monitoring either manually or automatically all servers under AMX since there are not much: http://www.amxmodx.org/newstats.php?mod_id=0&addon_id=2
Fun fact #2: in the second screenshot you can see "is_blocked_authid" function. At client connection, If you are validated with this check, your steamid and ip are automatically added to the ban list. For some reasons, It would appear that my steamid and ConnorMcLeod are blocked. Likely because we know this guy long time ago and this is not the first time he's doing some vicious and nasty things.
