Perhaps this could be implemented across the platform by simply not allowing upvotes after 72 hours?
It's easy for the bot owners to make this change, yes. And personally, If i was a bot owner I would go with this plan.
I would see this as a chance to make a big deal about it and advertise the fact that you are helping give time for 'the cat' to flag the 'poor content'. I think the Bot owner who takes this stance first will do well.
3/4 days is plenty of time to Bot a post, I must admit to waiting this long purely to let my followers who aren't around every day a change to get in before extra $$ comes so their curation is boosted.
Cheers!
