Does anonymity give rise to hostility?

So, how about improving the registration process and testing the new feature for 2–3 months? E.g. Five out of ten users get an invitation to create a user page and upload a picture; afterwards, we track how many of them got involved in conflicts with other users (compared to the group of users who were not invited to do so).

Any other ideas how to measure success?
