I like this, and even think that non-free events run by non-profits should be allowed, but I think mods still need to be active in setting limits:

What if there's a free open mic Tuesdays and Fridays? Can they advertise three or four times every single week? That seems excessive, unless there was sustained interest from the subreddit.

If, every week, there's a discussion about the upcoming performers, and the posts get upvoted, then sure, post again later this week and next week and the week after. If the posts end up in the negatives a few times, then it's spamming to not wait a little longer to advertise again.

So, like, I think it should be modified to

1. Allow fewer posts for recurring events.

2. Allow posts for non-profits even if they have an affordable entrance fee.

3. A warning to frequent posters that they should be cognizant of the interest shown to their past posts on the subreddit so they can avoid spamming.
