I have been working with XLoveCam for just like three years and they are a solid cam program.
You can promote their sites on XLoveCash and they give you a very nice 35% revenue share commission at the start which is really tempting for adult affiliates.
They are an European company and the majority of their models come from that continent.
I have to say that they have amazing promotional tools you can use on your website but they are not as profitable as Chaturbate is, at least for me.
I know many affiliates that promote them and they are a top earner for some of them so you should give them a shot for some time if you have a cam traffic or if you are planning to a camming website yourself.
