Sometimes I don't get a chance to share after posting on Hive because it's late, and on Reddit it works better for me to post at a different time.
Regarding the malicious aspect, I've seen that sometimes people pass off other people's content as their own. Users on Reddit comment on content that another user took from Hive, and some respond as if they had made the recipe. They also tend to do this with tourist sites or crafts. I know this isn't easy to track, but it doesn't seem like an act of good faith.
Well, I'm already taking measures in this regard, thanks for the information.
