It can't be automated but I assume I'm just going to throw them out. I get enough people spamming me with hundred comments a day saying I'm farming because I get curation rewards lol.

Hive Watchers ended up banning me when I questioned them asking someone to make 150 declined rewards posts over 150 or more days. As if that won't encourage someone to just make a new account. No one is going to do that.
