To add on to this, these posts don't really help us with the investigation unless they're introducing new evidence or alerting us to a current action that someone may be freed up to look into. When we handle these investigations, we're not just interested in catching the poster-kid/main culprit. We also want to identify what/how they're cheating and have that method completely detected so we can ban multiple people at the same time, and build a stronger case against particular companies. This means it may take some time until action is taken because closing an investigation isn't as simple as just banning one individual. They're more effective when we can use them to identify a group of cheaters at once and effectively lock down the use of a particular 3rd party prog.
Which is why we want folks to submit report tickets, because they'll always be looked at and invested thoroughly, plus it doesn't alert these 'cheaters' that they've got a spotlight on them which allows us to catch more.
Furthermore, if this thread was made about a North American, European, African, Australian, whatever company, it would be handled the exact same way. Does this feel like the best method for you on a personal level? Perhaps not, as you're having to wait sometime longer for action to be taken against someone who has wronged you, but it works best for us as it allows us to catch multiple cheaters in 1 swoop, as well as future ones.
Would you rather 1 cheater is banned, or 30 cheater are banned and the program they're using is detected so that future ones can be caught too? If it's the former for you, fair enough, but for us, it's the latter and that's why we'll continue to use this method.
