I just saw a post that referred to ChatGPT as "Mansplaining as a service", and it is so wonderfully correct - instant generation of superficially plausible yet totally fabricated nonsense presented with unflagging confidence, regardless of topic, without concern, regard, or even awareness of the expertise of its audience :D #chatgpt #mansplaining #GenerativeAiIsGoingGreat

Friends, it finally happened. On August 7th, 2025, the number of spamtraps intended to fool spammers rolled past the number of inhabitants in my home country of Norway. It's time for a retrospective.

Recently I found out that when I sent mail to GOOG hosted domains, they would mark my messages as spam or disappear then entirely.

Then today a mailing list host's spamassassin rejected my message.

It turned out that somebody had reported bsdly.blogspot.com (GOOG hosted, but referenced in my .signature) to spamhaus as malicious, and GOOG + the mailing list hoster believed them.

Got delisted, no problem. So which party is to blame here, or what method?

"backdoor" is the new "virus" in overused and wrongly applied terminology.

Over at the facesite I came across a piece (Not linking to that sh*t) about "Linux malware PLAGUE" which describes a piece of software that is useful *post-compromise* to whoever wants to hide their tracks.

Not a backdoor because it requires already established access.
