You can link your Reddit account to your Hive account on HivePosh.com. Then, your PeakD profile will show a Reddit icon.
Also, when sharing links to Hive content on Reddit, the Posh bot adds a reply to the blog to notify the blog author that the link was shared.
If the Reddit share sees some engagement (replies/upvotes), the sharer can earn some Posh tokens as a reward for sharing.
