amok: It would be interesting to see though. I think anonymisation in RepLog 1 is not so much a problem, as all posted here has agreed to be logged.
xyem: The anonymisation can be a problem depending on how I do it. If I just change the names, people will easily be able to match up the names to who they are by their current rep. Doing a random (but consistent for the user) adjustment of the rep to throw that off might interfere with people's analysis.
I think that there is 2 reasons for to ignore the ethics of anonymization in this instance
1 - we are all already anonymized via virtue of using aliases. Granted over own aliases has a meaning to us and is an representation of us, as long as you do not use your own real name as alias, then you are anonym. (like I suspect SimonG's real name is not really Simon)
2 - by posting in this thread we agreed that we would be logged, and part of the experiment. Agreeing to this removes some of the ethical problematics around anonymisation. Granted, as you yourself say, it is easy to find out who is who by publishing a log of rep with fake names anyway. It makes no sense having a rep log, and then adjust the rep's for anonymization, it screws up the data.
All ethical problems can be circumvented by adding a post, asking people who do not want to have a public log to tell you. You can then just remove them from the log. For ReLog 2 this can be part of your call for participants. In research, you do not need to have anonymous participants if the participants agree and understand that they will not be so.
