If you are sending out PMs to dozens of people, you might be encountering an issue with hitting the max PM/day limit. With you having >500 activity, it doesn't appear that whitelisting will result in additional limits.
it's not the per day limit. i don't have the error in front of me, but it states a 12 recipient max per PM. the quoted limits are not accurate.
i actually bumped that thread earlier today to inquire about the inaccurate limits in the OP, but a moderator deleted my post. according to that post, i should be capped at 30, not 12.
You can create a slack workspace, a telegram group chat, or some other off site platform to communicate more effectively with large groups of people.
very few people are gonna join a slack or telegram group just for this. it's a bitcointalk community event and the PMs are not unsolicited, so i don't see why using the PM system would be a problem.
