This is nothing.<p>I have a very common name and a very common surname and people have used my email (name.surname at gmail.com plus the infamous GMail variants such as namesurname or NameSurname) for purposes like accounts on dating sites, Spotify, Instagram etc.; invoices; banks and insurances; resumes and job applications; medical test results; newsletters and all kinds of personal communications.<p>"I" am a local politician, a Swiss or Italian banker, a boyfriend deserting some girl in Argentina, a rugby player, a professor or two; "I" buy screws, magic tricks, diving suits; I know several of "my" birth dates and addresses and I have easily identified a couple of correspondents.<p>In most cases there is no practical way to verify email addresses, particularly if the person is really convinced that their email is the wrong one or that some approximation is allowed, and without actual payment collections coming your way little harm is done.<p>I sometimes complain to web sites with inexcusable confirmation-less registrations or reclaim accounts on services I might want to use, but for the most part I just let incorrect emails accumulate to play the passive game of collating them and consolidating identities (e.g. is the person who follows cooking courses in a certain big city the same who received from a friend bus timetables for that city?).
