I feel, copying your own stuff is ethically sound.

Usually, depending on others material, it's safer to err on giving credit, even if to state anonymous. If you are cross posting, stands to reason, others read.

I once had a whole thread (not PC)'shared', with,a personal friend. All, names, dates omitted, doctored to look, like it was all me. Uncool, unfair, created trouble.

Here, in PC I've noticed, you can share links...each poster receives ownership, own stuff.
