It can work with anonymity, I think. Just need a moderately-useful web of trust to filter out scammers. I think we’ll see it. Some scammy accounts will still slip through, but it can be worth it for businesses/people that need to ensure fast exposure to more people. Up to each person though to decide if it’s worth their reputation to repost something for a few sats. I don’t like to do it most of the time. Usually I ignore those pleas for reposts, but if a company like Blockstream or some artist I like on here was making the offer I’d participate. It would benefit them, and me, and I’m okay reposting that kind of stuff.
