Hashtags for triggering PPV

Hello there, apologies for asking (Google hasn’t supplied me with any meaningful answers so yet, nor has the OF help website).

I’ve seen several other makers post things like “PM me with #BBG to access the video”

It appears that by utilizing the #, the message is automated and contains locked material. Does anybody know how to do this?

Thank you in advance xx.

I believe the creator you are referring to has a chat staff that works for them.
