You re telling the truth, btw the proxy server supplier disliked ur cmt.Please don't listen people who say use only mobile proxies etc. you can even use a VPN if you don't rush with your activities
You must use VPNs that thousands people useVPN especially datacenters trigger automatic ban when posting/commenting while logged in with that IP. I tried it myself even on subreddits with no CQS requirement.
they are probably detecting other things on acc as suspicious beside spamming, spamming and botting is the most common one. like they compare shadown banned accounts to other ones that suddenly are created do they act the same way or commenting a sub that your previous acc was banned in witha new one even if its hidden with proxies and anti-detect,(they probably can detect similarities somehow), also as of feb, they indiscriminately peoples accts anyways.Reddit accounts are a damn pain to maintain. My account got insta-banned right after posting, even though my content had NOTHING to do with spam.
