It might hurt their long term numbers but the person they swing the hammer at is also out $45 and no longer has an account with them.
RLC has a much larger audience with numbers that go far beyond what gets posted in Forums.
I myself don't understand their way they operate their business as what gets posted in Forums is a form of Free Advertising for them but they have a Policy in place and they adhere to it quite well. Anyone who opens an Account with RLC knows what their Policy is and what the consequences are if they should get pinched for posting Content that came from RLC's Servers.
RLC has always swung the hammer lightly for the longest while. Now they seem to be swinging it more aggressively over the last few months. There are a few other Forums that also contain Content from RLC and they are feeling the swinging hammer just as we do on this Forum.
