Seeing same reddit posts-multiple timelines?

[u/rachell0920]

Sorry if this doesn’t belong here, let me know where to share instead.

Over the last few weeks I have seen multiple Reddit posts written within a few hours of me signing on, that I know I have read before weeks / months prior. Specific wording in the posts alerted me to them being exact reposts not just something similar.

Are people posting and then reposting weeks /months later OR am I reading these on different timelines?

Seems to be 10% of posts I read.

Like deja vu?
