I am using datacenter proxies and was previously using the same IP for ages and never had any problems with bans. I recently increased my farm size from ~4 bots to ~10 bots, I'm not doing anything else differently. My bots are all now being banned within hours (like 4-5 hours) of creation. I even tried using more proxies (3/3/4 accounts per proxy), but alas 7/11 got banned. What's going on? In the last month or 2 of botting I've never had this problem. Is it the proxies? Is it the script (private script that I made myself)? What has changed from me increasing the size of my farm leading to all my bots being banned SO QUICKLY?

More bots on one ip are more likely going to get flagged and banned. Try to use an individual proxy for each account

And yes I am suicide botting, but my account previously survived a whole day or more, which is fine. But 4 hours is not.

And I would like to use as few proxies as necessary because as we all know, proxies are expensive as hell.

Non residential ips = suicide

Any advice where to find affordable residential IPs then?

Its your IP
Time to clean out shop and start fresh.

no one is going to teach you how to bot...just wait for another twitch prime promotion.
