Hi, @Mr DeaL!
There's no functionality to delay the comment responses. I have some clients with a huge audience, and I always recommend disabling the auto reply option.
Still… you could test setting the maximum options of random responses (around 20), but if you have a lot of interactions, it will happen again. 
Hope this helps...
Thanks
I had configured my ManyChat to send a message on Messenger after a comment, which was working well.
After the trial version, I was told that I had reached the contact limit, which is 1,000.
So, I deleted all the contacts I had, but it still didn’t work.
I finally paid for the subscription, and when I restart the automation, the messages no longer go to Messenger.
The responses in the comments still work, but nothing is going through on Messenger anymore. Even in my "Direct Chat" inbox, I can’t write to anyone on Messenger.
I need your help, please.
