ESEA co-founder Eric "lpkane" Thunberg says that it was his organisation's efforts that led to the recent VAC bans in the top tier of the CS:GO scene.
Earlier in the week, ALTERNATE's Simon "smn" Beck was banned on ESEA for a year for cheating, with the German player then revealing on Facebook that there were more professional players out there resorting to the same kind of tools he had been using.
After rumours about professional players cheating online and even on LAN began to spread like wildfire, it did not take long for Valve to get in touch with ESEA to learn what could be done to stop this new workshop cheat.
"We independently banned a high profile cheater, a german player, then worked with valve and shared our specific technique so that more pro players would get banned," he wrote on ESEA's forum.
"The results are starting to roll out with vac bans tonight, more to come soon."
