No, you cited your sources... so it's not plagiarism. It would be considered 'recycling' if you just make a second post with the exact same stuff and put it somewhere else. Many people accidently post into a community, then delete the post, and make it again and put it where it belongs. But, since the blockchain never erases anything, you can go and look at the data and if it's the same.... some will think it's fishy.

Many scammers will delete old posts and then a year or two later repost it as if it's new. So, never do any of that (which you didn't and aren't) but CROSS-POSTING is the option to take the post i just muted....and CROSS-POST it into a community more suitable and it will not be muted over there.... and it makes it just one post! It's basically a share function that doesn't double post. It's on Peakd.com i am not sure about ecency or hive.blog or the others.

You are not in trouble or anything... but do read the community descriptions and guidelines before posting into them.
