Most of the dull "viagra" type bogus http referrals are from the same top level domain (.ru). I'd like to add this to the blocklist but can't because I get the "The HTTP Referers format is not valid." error.
Can I just add .ru to into the table by hand or will this cause an issue?
I add maybe a dozen of these a week now to the block list and I expect this will be a performance issue eventually and I've never one had a non-bogus referral from this domain so see them as a waste of time.
I'm not sure I follow. I want to remove any and all url's that end in .ru, thus
Should do it. Is this what I am supposed to add?
I'd assumed that this would by default match any combination of characters before the dot already, but it seems that it must be a more complex matching as it still allows domains without a sub domain while removing all others.
