Have something happened to biting system? I thought links were supposed to be faded if the person has signed up for the virus you don't have/not able to bite, and not faded if you are able to bite them. But several people who have signed up for my virus, have had faded link, and some people who want different virus have had non-faded link. And so far I have been able to bite all of them regardless.

If this is not a bug or issue and I have just missed something crucial, feel free to lock this :P

could it be that the people you can bite that are looking for a different virus signed up for the 'random' option? because if they have, then anyone sufficiently infected with any virus will be able to bite them, but whatever they get the most bites for will be what infects them and they might be hoping for something in particular.

as for the other issue of not being able to bite users you should be able to... well, if you're sure you're wearing the skin for the appropriate virus then i don't know what could be causing the problem.

If your current virus has progressed to the last two to three stages where you can start biting for it, it overrides the skin you are wearing. Could that be the issue?
