Multiple BBC accounts - discussion

Without phone votes, I assumed we were looking at a 5 vote limit for everyone, with maybe some people making a 2nd account. Apparently people are getting VPNs involved... I heard someone say they voted 70 times...

What's the reality of this from what people are hearing or have done themselves? Do we think it's ok to do this? If this is going to happen anyway, should phone votes be re-opened?
