Meta question, apologies:

I submitted this exact link 20 days ago, and I've noticed several other precisely duplicate submissions recently. Meanwhile, sometimes I go to submit a link and I'm not allowed because there was a previous submission almost a year(!) ago. Just what the heck are the rules here?

Email the mods and ask this question. They won’t see it here and they’d take the time to consider and reply if you did.
