If I do a google search for "function tla_ads" I find 30,000 odd pages runiing TLA code (from the php install method). Have publishers on TLA noticed a pagerank drop and what server install have you used?
Both my sites running TLA lost 1 point in PR in the update ... I'd started a thread on just this subject, which has now disappeared .... spooky
I have some tla banners on a new directory that was awarded only pr 1, though I had pr 5 and 4 backlincks pointing to it. I don't think that's just a coincidence.
