what about daily "bumping up my post" posts?
No more than once daily. You shouldn't bump a post too many times in a row. Bumping shouldn't be annoying. Delete old "bump" posts so they don't clutter up the topic.
Interesting policy. I consider pure bump posts very very rude. If I can't make up any """news""", I don't bump my threads.
If bumping is all fine with the mods, could you please introduce a checkbox "bump up once per day" so I can bump it without cluttering it with "/bump" posts? Aka I don't agree with pure bumping being all fine as it is the opposite of the often requested feature of rating posts and threads.
