@razvanelulmarin It's impossible to plagiarize yourself. Reposting old content is the norm in the content creation industry especially while a popular figure is out on vacation.
New rules mean that after 30 days your content no longer generates revenue anyways which also mean's it's likely to be pruned and lost forever.
Therefore, wait 30 days and repost if it was popular.
It's your content, you made it and shared it. You didn't give it and you didn't sell it.
If any of the spam detection bots start seeing it as spam, like @anyx said, the community can always flag the misbehaving bot and it will be taken care of accordingly.
That's one of the issues for me, I don't want to be flagged for nothing. But it's true that the community has been very responsive to abuses.
Thank you for your input!
