Ha yea it's always interesting to check out the profiles. Some are using AI comments and churning and burning, and others are pretty sophisticated.
My thoughts on churn and burn = i would if I knew I could get new accounts up and running easy
If you're new to this, before you go scorched earth with your primary account(s), I would read a bunch of the threads on here over the past few months. Get familiar with proxies and antidetect browsers. There's a learning curve.
I lost every account I purchased (~12), a mix of aged and new accounts, and I THINK I did everything correctly. The aged accounts were great while they lasted, but lost some because reddit wouldn't acknowledge I verified a new email and kept sending a password reset to the original creator of the account a few weeks in. Reddit said i was suspicious a few other times and sent an email, but the email provider lock me out for suspicious activity (from the person setting it up). None of them were from actual comments getting flagged or getting the account banned.
All accounts I'm manually creating with verified emails seem to stick (static residential proxy). I'm able to post in a few subreddits and start gaining karma. But new accounts from suppliers get banned as soon as I post, even after days of logging in, warming it up, etc.
It's SUPER time consuming to manually create accounts, warm them up, etc.
Hope this helps. I'm not an expert, just my experience over ~6 months of tinkering with reddit with some successes.
