I’m also not sure of the exact post with the comments, but I do know which user you are referring to. It really has gotten to the point where you need to know the 100 hidden rules for a community to post unfortunately and I would hope we don’t go in that direction here.
My worry is that if we get to the point that we have new accounts spamming OF promotions every day it will get both cumbersome to block everyone and deter future legitimate posts. In the end it comes down to what is accepted by the rules of the community and the moderation and this will vary wildly with how small the population is overall.
