I have been (slowly) migrating to using my real identity in all places, which has left a strange mashup of identities in some areas. Really, I should get rid of the old identities (which will be difficult, no longer having access to all the email addresses/passwords/whatever of accounts I opened 10+ years ago), but my actual real name is relatively "clean". I have a couple of "incognito" identities which aren't easily linkable to me (it's probably possible, I haven't ever been particularly careful, but I try to keep them separate), but other than that I'm slowly trying to migrate into using my own real identity now.
