ReefCentral already blocks AlgaeScrubber.net... if somebody posts it on a thread, it is automatically changed to "clayboa". I think they do this in PM's too, but not sure. But now looks like they're are even blocking searches for scrubber info; if you do a search for "algaescrubber", you get "We're sorry, you've encountered an error". Maybe it's just me, but I get the same error if I search for:
scrubber
scrub
ats
turf
walter
adey
Can some of you try it and see what you get...
