@strypey@mastodon.nzoss.nz, did you post this on the NodeBB community forum? (See screenshot)

I did a cursory check and it didn't look like you posted anything like that, but my search-fu isn't that good.

If you didn't, then spammers are starting to steal content from existing fedi users and post them places in order to pass as real, likely with the intent to edit the post afterwards to add spam links.
