We realise that our spam filters are occasionally going to throw the baby out with the bath water, so to speak, but I'm afraid it has to be like that if we're going to fight these spammers off.
I would hope to be able to moderate the severity of the filter fairly soon, but for obvious reasons I'm not going to announce when that will happen, or even when it has happened.
I know it's a pain for you, and all I can do is reiterate what we've said before - that we're sorry, and we hope you'll bear with us. For once I can say with absolute certainty that this isn't our fault. It happens because of our site's high profile; it's truly the price we all pay for our popularity.
