This is a flood protect plugin.

There is many posibility to flood a HUB and make DoS like attack.
Verlihub is very strong, and doesn't crash, but bot(s) could cause slowdown.
Attackers could run bot(s) that makes many connections with the hub (probably from 1 ip address) and does private or global chat flood,
even worse passive search flood.
Passive searches could heavily slow down the hub's because the answers comes across the hub. Think that you search for a "." (dot) character.
There will be many answers from other clients.
This simple plugin's main goal is detect this kind of attack, and kick the bot(s) the connection.
The only problem is that the bot(s) can continue connect to the hub, so we save it's IP address to prevent it joining to the hub.

Features:
*Detects many kind of flood types
*Reports flood to OpChat

You can compile this plugin as you did with other plugins like forbidden words filter...

Thanks to Verliba for helping me make this plugin.
