I’ve recently seen a small flood of my personal and work emails (and group aliases) getting responses from many other companies’ support emails, as though someone were opening support tickets using my addresses. Is this some weird variant of push bombing? Or maybe someone getting me to train my spam filters to reject support emails so that Ill miss an important one (like “we’ve received your request to transfer your domain name; reply to cancel”) or such?
