Eventually? I very much doubt it.
The first imposter began his life on 07/18/2011, named Melanie Wandsworth (melaniewandsworth1) e29fb978-b1ba-4f36-9e87-38183abbcacf and has since then continued all of this in a daily routine, adding imposter-alts of friends. Meanwhile there will have to be more than 100 Abuse reports on this matter.
But of course this happened before to others as well. And even though confessions of this have been made in chats and Abuse reports have been written I can still see two imposter alts online, for more than half a year now, writing people in my name, sending messages from worn objects, parking their Ava's in places I used to visit showing nasty and sick profiles with pictures that have secretly been made from my person, impersonating me.
But it is not the stalker who bothers me most. You cannot help some people to do strange, violent, forbidden things.
It is the way society deals with it. In this case it is also the way permanent TOS violations are reported but lead to nothing at all. The stalker is proud to be doing this for more than 4 years now. Though it's actual main Ava is only 2 years old. I have talked to a dozend persons who had this happen to them before it happened to me. They did file Abuse Report after Abuse Report, some finally gave up, some left SL, some deleted their known life and started a new one.
