Some profile information has been changed on a regular user account and the user himself has not changed it, nor is there anything in the admins activity log that points towards that an admin did it. All profile changes that are logged have also only been done from what appears to be the user's own IP-addresses (different ones), even though he hasn't changed the info himself or had anyone using his PC or any other PC in the household.
What other options are there? Apparently no admin changed it since it isn't in the activity log, and there are no traces of any "foreign" IP-address regarding this account either. Most people would obviously say that it's the user himself who did it, but as I've said before, this isn't the case.
Can an admin change the activity logs to make it look like he didn't do it even though he did? Can an outsider log into the user's account and make it look as if he's logging in via the regular user's IP-address? I have no clue how this works, or how it's even possible, I will understand if you can't give any answers.
