Reddit Posting errors

I am trying to post on a backup reddit account. I use to do the posting for me.

I use an anti detect browser with a 4g proxy.

I keep getting this error every time I run the seneraio and usually get account bans.

[[“RATELIMIT”,“Looks like you’ve been doing that a lot. Take a break for 9 minutes before trying again.”,“ratelimit”]]

I understand this may be an error on reddit side however when I try post manually it seems to work fine. Does anyone know how to get around this?

Also does use reddit API to make posts?
