Reach out to valve and tell them that you won't support them until they fix the bot crisis. <---

The bot problem has been going on for years; so long as valve is making money, they have no real incentive to help the community, and so their effort will be put towards profitable updates instead of combating bots.
The longer the bot pandemic lasts, the fewer amount of new players there will be joining the community. Please do your part and help make team fortress 2 a better community as it once was.
