This is third report after a little break on the reports, even tho the curation never stopped, so that is why you haven't been tagged in a while.

Not 100% of the users that send links are picked up all the time, specially if they are being curated already by other means. We need to distribute the votes.

All the curation systems that create reports are independent from Premium, in fact you might be already curated as a premium user, hence the post will not be picked by the curators.

And stake based curation has a limit of links that can be sent per tier, you can check which is yours in the report.

I hope this clarifies it.
