At the risk of looking like an idiot here, I am going to ask it anyway, What is the main reason people do the DDOS attacks? Is it for the sole reason to crash the sites, are they getting any information from the sites they are attacking? I just don't see the point of doing something like this just to bring down a site, because the site is going to come back anyway.
I can see that by attacking casino servers, that is going to cost the casino money, is that what they are trying to do? I remember when CM was hit, but I don't remember how long the site was down, how long have the TopGame sites been down?
Hopefully, someone will catch these people or person, and hopefully they will not get a slap on the wrist. It will be interesting to see how this ends.

When it comes to extortion (a fancy word for criminal blackmail) these DDoS creeps play on the fact that downtime is expensive for operators not just in terms of counter measures, but lost business.
Many of the classic DDoS attacks have been carried out on major sportsbetting sites, and have been timed to coincide with peak sporting events when the volume of wagering is at its height, thus losing the operator significant amounts of betting revenue.
The crooks will usually apply the DDoS pressure to show that they have the capability, and then demand a ransom from the operator to be let off the hook. The sum demanded can be in the tens or hundreds of thousands, but is the more economical answer than the lost business the attack is inflicting. Some have paid these ransoms, others have wisely looked at the long term threat of repeated attacks and refused to pay, instead working with the police to catch these buggers, and beefing up their defences against future assaults.
There is no doubt that this is out-and-out criminal activity, and where the dedicated cyber-enforcement units find these nasty folks, they face severe punishment.
Launching DDoS assaults for other purposes is just as criminal, because it either seeks an advantage that is not legally due, or maliciously damages someone else's business...so these creeps, too, face serious penalties when caught, not to mention civil actions for pecuniary damages. That applies to both the perpetrator and those who have contracted with the perp to commit the offence.
Looking at that anonymous post from the GPWA above (the guy doesn't appear to have the guts to stand by his own name

) I personally feel a sense of revulsion at the mafia-style antics of these people, which do not reflect well on the industry as a whole imo.
The lack of morals and the unprofessional behaviour of all concerned is just disgusting, and it's a pity there are no mechanisms that would enable the industry to rid itself of these creatures.
It does not appear to have occurred to any of them to approach the problem in a businesslike way through litigation...especially if they have, as they are claiming in this distasteful public wrestling match, convincing evidence of who is responsible.
