That said, I did dig up three actual lawsuits (see above) that these bastards have apparently filed over a single image. No information about the case actually proceeding and in each case Oscar is mentioned as having never responded. Makes me a little nervous about the letter-writing program, but still.
can you please supply links to these 3 cases you mention, I am going to look into this, but I suspect that masterfile is mentioning Oscar and him not responding to "ding" him and his reputation.. Trust me if Oscar was "retained" to represent someone he would do just that, he is very well known and respected and he would not simply blow this off, as it would be damage that reputation.
As stated previously the letter program is not the same as retaining his services, and he is not obligated to respond to anything he is not retained for.
