Notification for topic I have no relation to

This happened to me 10 hours ago:

I received a notification for this thread:

I have never participated in that thread, seen it before, and I've not logged into this forum for weeks/months.

You have a problem.

The notification appears to have been generated because a user linked to a topic in which you had been active.

This comment >> linked to this thread... it is possible that you are subscribed to notifications on this (linked) thread and/or it is possible that one of your specific comments was the target of said link (it doesn't appear to be at this moment, but possible the user had done a quick edit immediately after posting).
