I did one day in Llandudno and been inundated with calls since because of Kommons and they listed services that I don’t do. I will use that email address thanks.
I had my pictuures and number on around fifteen different sites at one point, i now copyright them, which prevents any tom dick and harry taking them. Since doing this ive not had any random ones take them!
Some sites that advertsie with AW are still using them, but thats an agreement with adultwork i believe as its not false advertising its straight to my profile and my details.
I always keep an eye on vivastreet too, usually in London i have seen my pictures used, they try and crop out the copyright, so i tend to put it right in the middle of body parts to prevent this. I have an account manager on vivastreet who i call in regards to these adverts and they are removed instantly as she is familiar with my pictures.
I do think taking the time to copyright your pictures really helps keep them your own!
I use WatermarkStudio. its brilliant, can place it where you want, change the colour and transparancy depedning on the pic!
