By blank do you mean absolution is blocking them? Are those in the blocking file? I didnt look for them since like I said absolution said 'exact match found in block list when I whitelisted.
I tried clearing dns cache... no change... tenforums still works, and sevenforums does not.
Fyi, I did not try accessing seven forums with absolution disabled (this seems to have fixed tenforums). I am pretty sure I could get it working like tenforums, but I left it as is to help diagnose the problem.
...another datapoint...
I rebooted the router, and now tenforums is once again blocked...weird behavior
