In this question Why doesn't a photon state have to be infinite in length? in the answer given by [user A] there is a comment by [user B] that is advertising his/her personal theory on photons.
I commented on this, and [user A] answered:
I have long since given up on the duo who love to go around every question mildly related to theoretical issues and spamming their pet theory views. It would be helpful if we can flag comments for non-mainstream physics.
I think this is a good suggestion, if it can possibly be implemented. Maybe even if one could flag comments like this for moderator attention it would be enough.
BTW today there was no link to Physics.meta on the page. I had to search on the net.
