Block Random String Comment Spam

Recently WordPress sites have been getting hammered with random-string comment spam. The attackers are clever, using random text strings for every vector except the payload, which usually is the URL used for the comment’s Name link. But for these weird comment spams, the apparent payload is the email address. It’s the only part of the comment that’s not made up of random gibberish. Continue reading »

DIY Server Uptime Monitor

So decided roll my own DIY server status monitor and share it […] Continue reading »

I disabled AI in Google search results. It was making me lazy.
Went out walking today and soaked up some sunshine. It felt good.
I have an original box/packaging for 2010 iMac if anyone wants it free let me know.

All free plugins updated and ready for WP 6.6 dropping next week. Pro plugin updates in the works also complete :)
99% of video thumbnail/previews are pure cringe. Goofy faces = Clickbait.
