I keep getting the captcha

I keep getting the captcha to verify that I am not a robot. I have read some other bug reports and I have seen that SA moderators have confirmed that it may be a result of a shared network.

But what I cannot find is a way to verify myself as a member of a shared network - i.e. a way to input that I am not a a robot once and for all.

I am using my university's shared network.
