Of more concern, any eavesdropper between you and Wikipaedia (or any other website) can run a 'Checkuser' on you.
I understand that you are paranoid. That doesn't mean you need to try and make other people paranoid. Eavesdropping on a connection requires a fair amount of skill and effort, so unless you have serious enemies, it's not likely to happen. Also, I would imagine eavesdropping to find out the source IP would be rather difficult - you would have to catch and analyse every packet going into the Wikimedia servers to find which ones are from the person you are looking for.
