help for reddit accounts

Hello, I always need to work with many reddit accounts but for several weeks something has been happening to me, when I buy the accounts and open them, when I make a post to upload karma they close them or they close them the next day, this did not happen before, I am using dolphyn anty and I'm using 4g on my cell phone, when I want to change IP I put airplane mode on and that's it but I see that it's not working for me and I don't know what to do.

I would like you to help me, I suppose I have to buy proxies from the country where the account was created, right? I say this because the accounts you purchased are from the USA, what type of proxies to use for Reddit accounts? where to buy those proxies, I hope you can help me please.

who says you have to use the ip from the same country? I have accounts i created in some 3rd world shit hole no one has almost ever been and they are working fine on dirty US VPNS even while i warm them up and out of many im warming up now none have been banend

i dont even use antidetect browser either when posting and i login in a crapload of accounts

Matching account previous IPs is not that necessary. Try to change your posting pattern, or find out if your content gets downvoted or reported.
If so adjust a bit and see if the rate of bans remain the same.

You can try out using different countries IPs for account

Matching ip countries isn't needed. If the accounts get banned for posting/commenting anything on a normal browser then they're at fault. But if you're commenting links or text that may be flagged, you have to ensure the content you're posting isn't the culprit.
