Do you really think that someone gets to work and isn't instructed that there was a banwave? Let's be real... they knew about it when they started answering tickets.
And the whole hacked account thing can work on days other than a banwave. If they flag an account weeks in advance like you say, then they'd find it pretty convenient that the person ends up claiming they were hacked the day of the ban and not weeks before.
Like I stated before, I just put what had happened to me in the hopes of helping others. I even stated earlier that this might be a fluke occurrence after reading other articles. In no way was I ever trying to mislead or misinform anyone and to accuse me of that with no proof is ignorant. What happened to me can be similar as to why some botters missed the ban wave... It's just random and was a rare occurrence that shouldn't have happened but did.
