I personally haven't come across any "rate my start-up" posts I'd considered spammy, but maybe that's because the measures that are currently being taking have been effective (marking as dead, lack of upvotes for spammy posts). Mostly I've only seen that kind of spam in comments.
As for RMS posts in general, I really enjoy seeing what other people have done. So I would be opposed to an outright or unnecessarily restrictive ban.
