Unfortunately there is no known way to easily stop DDoS, it's a problem that's being researched intensively by computer science majors and it's something that affects not only our league but a lot of companies along the globe.
I actually doubt that companies that assure to prevent DDoS attacks and charge a huge amount of money for their solutions can actually ensure to stop DDoS's effectively and even if ESEA were to apply some DDoS protection system it would probably make the league fees skyrocket since none of this companies offer a cheap solution.
So far, and until someone develops a good open source system to stop DDoS attacks, it's up to each one of us to ensure that our IPs are secured so that we don't get DDoSed. For which I suggest the following:
- Beware of IRC clients giving away your IP when auto connecting to a network.
- Beware of Skype giving away your IP when directly calling a peer.
- Ban bape from everything everywhere.
- Do not under any circumstance play in a server owned by bape.
Just a few simple steps that will help you go through open playoffs a bit more safely.
