Wikipedia Spam Filter Notice

Question

I've been an occasional Wikipedia editor and user for many years. Twice recently when I tried to make a minor page edit, I received the following error: "Spam filter notice"

Your edit was not saved because it contains a new external link to a site registered on Wikipedia's blacklist."

However, (of course) I added no spam links and none are visible in the claimed highlighted text.

Answer 1

This makes no sense at all, but somehow the Chrome LastPass extension is triggering the spam filter. I tested this by opening an incognito window and performing the identical edit, which succeeded.

After that, I disabled all plugins and enabled them until I found the culprit. I guess I'll have to temporarily disable LastPass whenever I edit Wikipedia for the time being.
