This happened to me recently, there’s a group of people confusing me for a humanitarian artist because I stood up for her in front of the wrong people, and now I notice my copyrights/trademarks are intertwined with hers because the misconception is socially innate.
I get this sometimes if i wear my black work polo to a shop after i finish work, though i take a small bit of satisfaction in saying ‘yeah no idea mate’ and turn and walk off and keep browsing. They usually stare for a few seconds with mouth open before they realise the assumption/mistake they have made
