@dominateofyou Worry not – I've never deleted anything so far; and if I had to remove threads (mbox full, for example), I'd remove those which are alreada several years old, and the person is no longer a member on SW.
I don't know what your definition of "old" is but if it is older than 3 months, I am not among those that you cleaned. Now that you know me, how about cleaning my old in box?
