He means you could have been
banned just by
nick and/or
username ...
YourNick!*@*
or
*!*
YourUsername@*
or a combo of both
YourNick!*
YourUsername@*
So even if your host/ip has changed, if you use the same
nickand/or
username, the ban mask used will still be effective .. so
try using a different
nick and
usernameEdit: Mentality, after reading the next post ..
