instagram is filtering my posts

Any suggestions for automated posting with a lot of accounts on Instagram?

I post on about 20 different accounts with a ton of different pictures and captions about every 10 minutes. It's pretty slow but still posts are getting filtered from the hashtag.

I use 1 proxy per instagram. Does anyone have any suggestions on how to stay under the radar?

I recommend posting slower and on less accounts. You are probably going too fast so Instagram knows you are a bot.
