I posted an answer to the question FileZilla Server refusing connection - 425 error, where I copied an IP address from the post.
I now find that this IP address was replaced by
both in the post and in my answer, but no revisions are logged to that effect.
In addition, while the IP address was written in my answer in the format of
XXX.XXX.XXX.XXX, in the post it was rather written as
but it was still detected and changed.
What person or automatic procedure is responsible for these changes, and without leaving any traces behind ?
