Don't share Hive links in subreddits dedicated to Hive and its projects: HivePosh doesn't reward this activity because it mostly exposes Hive to people who already have Hive accounts. There are only two exceptions to this rule: r/Splinterlands and r/Holozing.
Sometimes users create subreddits about Hive and hope that HivePosh will support them. If you want to create a subreddit, choose any topic other than Hive, get at least 200 subscribers, and then HivePosh might start voting for shares in this sub provided it's a real subreddit, not just a place for dropping links.
OK.
