Is that ok to do here or is it expected / desired to have some accompanying text to go along with it?

If it's your content, don't worry about it. If it's not someone will pick it up sooner or later. You can't get 'paid' / rewarded for the work of others. There is a lot of plagiarism goes on and a corresponding lot of HIVER's looking out for it.

The place gets a bad name for this, but if it's all you work then you post with confidence. If it's somewhere else on the internet, then you may be asked to prove it's really you on the 'other account'.

When there's $$ involved, people do all kinds of things to get it.. including nicking other people's content.
