Do not use URL shortening services: always submit the real link.
Begging/asking for bitcoins is absolutely not allowed, no matter how badly you need the bitcoins. Only requests for donations to large, recognized charities are allowed, and only if there is good reason to believe that the person accepting bitcoins on behalf of the charity is trustworthy.
News articles that do not contain the word "Bitcoin" are usually off-topic. This sublemmy is not about general financial news.
Submissions that are mostly about some other cryptocurrency belong elsewhere. This sublemmy is exclusive to Bitcoin.
As far as I can tell, all these points apply to Monero equally as well.
