The user would take the poshtoken comment of their share, like example this (even tho I wasn't the one who shared it)
https://peakd.com/hive-105786/@poshtoken/re-armandolnrs-vywouboc-6458
post that as a comment under the POSH curation posts, the curators would then in the next one compile the best tweets mixed with some great posts they curated.
As for the distribution, as far as I know the bot can handle sharing the rewards if there are more than 1 sharer, though I can make sure that's the case with the dev first.
Perfect thanks
