[Xastir] non licensed callsign in my area

[Steve Rogers]

 I found a possible illegal callsign with passcode 9922 on my xastir program, He was running a iphone app from the internet. I found a passcode generator online and typed impoop and received a aprs passcode.

   I turned off my Igate which gets little activity here, the passcode generator was N5DUX but found others online. Is there a way to block these intruders?
