I'd suggest to stop pushing a false sense of security on people
I've seen the sql.pro mod, and it's easily hackable >,<
All it does is make a few calls to stop a few SQL injections and it malfunctions quite frequently telling all users they tried an SQL injection. There are numerous types of hacks, not just SQL injections >,<
IP hacks
Session Hi-Jacks
Local File Inclusion Hacks
Remote File Inclusion Hacks
Shell Uploads ( the worst they base off of RFI )
Tons of differant approaches....It's very rare i find a game that was made by McCodes I cant use one of the above Exploits on. For awhile I was going around doing them then telling users the fix, but to many are unappreciative so I stopped.
