[Solution Required]Subreddits getting Banned again and again

My reddit communities are getting banned again and again, and I don't know what's the reason. I tried multiple accounts but no effect.

When i create a community and post first post everything is ok , but when i add second post it gets banned without telling me the reason.

I am not spamming or something like that i want to grow it and use for online business

Any suggestions from you guys? What should I do?

maybe your account is not aged enough to create a solid subreddit

What are those subreddits about? Maybe that's the problem

Make it aged a bit and do regular comments and likes. 3 days a week is enough. on week 3 you can start posting your own. And use a residential proxies/IP

You need more karma and an aged account
