I have a case where I couldn't take a SS for it, since it was the time when servers were ddosed the hardest I banned the banevaders and those who were making lag on the server. I only know that when ever I banned this one case servers started to lag for maybe 20 min approx. I have no proof, just intuition. Whether it's coincidence or not, but this situation just didn't make any proof lol
But I agree certainly no proof no case!
