In either case, though, the server should try to deliver it once. The issue with bae.st/SPC/FSE was that if a 150 people on FSE are following someone on one of the other two servers, and that person clicks "Like" on a post, then that's 150 attempts to deliver the Like, and multiply that by the number of times that person clicks Like and the size of their bio. If it's Create instead of Like, it's an even bigger deal.
