Report an Agent?

Client reached out, saw a property on instagram. Of course, the first thing I’m going to do is look at the posters active MLS listings to find it- nothing. Well turns out this agent posts numerous videos of other agents listings (which is wonderful) however she is not disclosing the listing agent and passing these off as her own. As a listing agent, this would frustrate me.. likely these agents don’t know she’s doing this. I texted her and she said she’s never had an issue, but in my opinion this is just shady and I don’t want people doing this with my listings. Would you report it?
