I know somebody who was a member of a forum which uses a heavily customised version of vbulletin 4.0 and they used to create a new account on their Android smartphone every time they were on a different connecton, and would make sure their cookies were cleared before creating the new account then closing and reopening Chrome to ensure that the cookies were cleared. They were using completely different ip addresses for each account but then they were eventually told by one of the moderators that a database analyst ran a check and found x amount of accounts matched to their device.
Is it really possible to detect if a user has multiple accounts not by ip addresses or posting style but by device in particular by doing an database check?
