One thing, though, is that not all Reddit groups allow hive links
Yup. Every subreddit has a list of rules on the right. Some don't want links. Some even say you can post a link but you should be a creator of this content. Or r/Vietnam (1.2M) says "Travel blogs/vlogs are generally discouraged" so you can understand nothing from this. Some mods ask to engage in the sub and only then you are allowed to share your links. Etc. Much depends on how good the shared Hive article is for a particular sub. Some subs openly say "If you self-promote and we see only shared links on your account, we'll ban you". So... Read the rules when you join a new subreddit.
That's why we collect Hive-friendly subs to make it easier for new people to join the program: here and look at the top comment below, some more subs but still not included in the table.
You should revise how you share links - look at the rules above.
This is a preview of your share, no link is visible. Your previous shares were counted for contest #4 since nobody told you and you are new on Reddit.
