Rae, hello!
I must confess that I personally do not have a solution at hand, that's why I said we
will discuss the best way to address this point.
It is a complex issue, that includes security, but also efficient responses to IP
blockages, that's why I mentioned both WMF and the teams involved (e.g. people that
deal with this type of issues, stewards, event organizers etc).
Cheers,
