They often use either fraudulent or stolen accounts which has its own penalties once discovered. Another poster reminded me they bypass using low currency region locks to buy very cheap accounts, which doesn’t quite equate to a full USD/EUR account sub.

An ex-dev that worked at Blizz about the efficiency of banwaves
I see often that people suggest that Blizzard profit off bots (Credit Fraud/Stolen accounts etc)
Do other games like Runescape or CSGO also “benefit” from allowing (aim)bots, using them for inflating sub counts or purchases?
Some accounts also get stolen with phishing methods or used with fraudulent credit cards, that incur chargeback merchant fees for Blizzard. The “paid” amount plus penalty costing Blizzard a lot more not to mention the damage the botters do ingame.
But wait “credit card fraud doesnt exist for games!!” Some people forget, that Visa stopped processing payments for Runescape because the occuring fraud was just that extreme at a certain point in history.
One of their last public numbers revealed close to 271k banned in December 2023 alone. I don’t think it was even the majority of them.
Better solutions?
There’s no game so far on a similar scale that has a solution. This problem is literally everywhere and anti-cheat development has yet to outpace the illegal bot development.
