Monopoly Events run scores of conventions, including Comic-Cons in Edinburgh, Aberdeen, Manchester, Liverpool, Birmingham and the north east of England.
They also organise specialised events dedicated to the likes of professional wrestling, horror and anime, featuring celebrity guests from across the world.
The announcement has been met with mixed views by fans.
Some praised the decision, saying they had no desire to be “plastered all over some drab blogging YouTube page”, with others saying they did not like the possibility of children being filmed by people they did not know.
One fan wrote: “It’s one thing walking around with your phone, which someone could see and ask you not to film them, but your glasses aren’t as obvious.”
