Currently, gambling signature campaigns are dominant on the forum. As far as I know, philipma1957 is not particularly active in that section and the casinos are not open to generous rewards per user. With the departure of mixers, high-payment campaigns have also gone.
I speak from memory but I would say that I once saw phillip say that he had problems with gambling in the past, probably that's why for him joining a gambling signature campaign is something he doesn't even think about. And although there are other options, they are limited, although he should not have any problem to be hired. He is the human with the most posts in the forum (the first is ChartBuddy), which is attractive in terms of SEO, and the second most recognized.
By the way @NotATether, I checked your post history and you are crazy dude (in a good sense). You posted 26 posts on 8 February, while 18 posts were posted in one hour timeframe. How can you check threads, analyze posts and then write new posts in one hour? That's roughly 1 post every 3 minutes and you are not a spammer though, you are an alien (NotAHuman).
Well me recognizing that NotATether is a good forum member and a high quality poster in general I have complained to him a few times that he had not read before replying in some of my threads, and with what you say I am not surprised. If he writes 18 posts in an hour it's because he doesn't analyze much in some of the threads at least.
