I've been using them since way back when they were on earlibird. It's not perfect, but it has reduced the amount of times I show up in these sites significantly. The only disheartening thing is that most of these operators seem to just dump in batches of data periodically, ignoring any prior requests to remove so it has to be done again (which is fine, that's what you pay their automated search and remove request feature for)
