I understand the worry about scam surveys, hopefully I can clear up some of your concerns:
1) Students do get different domain emails than staff and the random numbers in the email address is my student number. (I’d much rather they used our names but that’s just the way the university assigned emails are.) It says as much on the TU Dublin website in a few places:
https://www.tudublin.ie/for-students/student-login/city-centre/
https://www.tudublin.ie/emailproject/students/
2) When you send a link to a Google survey, it gives you the option to shorten the URL. The (very long) original URL is docs.google but when you shorten it, it becomes forms.gle . You can check this yourself if you have a google account.
3) Posting a survey online like this does of course mean people can answer falsely or inaccurately, it’s one of the major downsides of anonymous surveys! But this method does also have its strengths and isn’t too uncommon for research like mine, and this isn't the only research method I'm using for the project. Either way, that does seem more a question about the validity of my results than whether the survey is a scam.
