Should Microcosm show the real identity of users?

I'm basically a cynic and think that any website, forum or whatever thats wants my real details, other than bank details and stuff for internet shopping purposes, is harvesting information, building profiles and trying to market or spam me with something now or inthe future.

This is very true, an example would be Evans Cycles' insistent on asking personal details in order to sell promotional good and the like (as well as help their marketing by selecting the appropriate stocks for specific shop).

I always get in trouble for not filling out the forum when customer declined, glad I'm not there anymore.
