The only way to possibility stop an DDOS attack is to have an big enough firewall to prevent the incomming attacks. But still, it wont stop it.
Most people that actually DDOS dosnt use a program. Wich would be retareded since they would use their home internet or proxy..
Some of the populated server trying to keep above 100 mb internet to make sure if there is an ddos attack, it wont hit it that badly.
Busting someone that is ddosing need alot of proofs.. First of all they have to find the IP where the attacks is coming from, then trace them to wherever they are, and etc.. It's not that easy as you think...
There is really no way to stop an ddos attack to hit any servers. There is alot of booters out there that could do easily 1gb attack or higher, wich would easily take down the LFS Master Servers..
Only way to get ride of an ddoser is to let them keep doing it until they get tired of it.
Keep making post about it just encourage them to keep doing it more. So first step, IGNORE it. Second step, keep figthing.
And banning them wont stop making them ddosing. trust me
