Sort:  

The bot was strongly downvoted because of spam accusations. It seems like it's advertisement was a bit too aggressive.
Now the bot has -1 reputation. It's comments are automatically hidden.
Who would respect and use such a bot?
Even if the current users stay with the bot, new users will avoid it. Without reputation, the bot can no longer grow.

I don't know what to do with it now.
Do you have any ideas?

That's rough. Yet your bot seemed to only follow your resteembot. Well you could always rebuild it. Or try the steemchat to st how you can get the flags removed.

I recommend @resteembot as alternative.
