I've been with them for nine years, but they don't care about turnover. Their goal (judging by their posts on their blog) is to have a lot of customers. Rather than taking a quality first method to achieving that, they're just packing everyone in as fast as they can.
Meanwhile they are shorting their long-time customers but I guess that makes sense. Many of us now get greatly discounted/free/get paid to host ad DH because of all the customers we've referred. If they get the old guys to leave, they wont have to pay out anymore.
Unfortunately, the tactic they're using has always been proven to be detrimental for the long term. There's a ton of names for it, none of which have a good connotation.
Alas, they still seem to be trying, at least. Michael is often very helpful so I still stick around. They don't have to post in this forum, they don't even have to say they're trying, but they do. Maybe I'm becoming a victim of PR.
