Thanks for your replies.

As far as safe, I mean could it be used for a DOS attack, like RMGir suggested? Will it provide a weakness to hackers to access the server? Could it cause the server to crash?

It looks like so far thought there isn't anything major. The only information we hash, I think, is info from our own database. I guess bad info could get in there though. I'll keep a close eye on this issue through our development.

Thanks again!
