1. I hate this crap about ISPs tracking back people and turning them in wont happen.
2. The only people who will deal with DDoS is IC3 or DCIS in order to contact them you have to have a lot of information on how the botnet it's self is operating.
3. The kids just making relentless useless threats quit shitting your pants over it and run your damn server.
Do you think any website would be out there right now if they shit their pants and shut down every time a threat was thrown at them?
4. If you get DDoS'd you get DDoS'd but that's when you learn how to handle it, Firewalls wont always do you so good.
Hardware Firewalls can help but if the DDoS exceeds your line bandwidth considering you're running on a home system this would be fairly easy to do then you're screwed.
If you're running a dedicated box the good thing is before it hits your system it has to go through larger 1GB pipes from providers to reach your server and with a good enough data center the traffic is usually filtered by hardware firewalls to the point it wont flood your port.
Anyway DDoS is a lame fucking subject, and I hate kids who turn it into a big thing.
You can deal with it, and threats are threats.
You're not gonna go tell your mom if some one threatens to punch you are you?
You think fame or TheDefaced would still be up if I ever just took the shit down because we got DDoS'd or threaten'd for it?
We've been smacked with up to 4GB/s of DDoS on our port previously and we just dealt with it, some times I wound up personally tracking the botnet down but that's what drastic measures are needed some times.
As far as a crappy private server for flyff, tbh who would waste their time DDoSing something like that.
