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.
