Afterwards, I went searching for the cause and found this forum post, which explains that the problem is caused by the Mozilla Archive Format extension, which has a setting that even affects pages not saved as .maff. To fix the problem, go into the MAF extension settings and change “When saving complete web page contents:” from “Take a faithful snapshot of the page” to one of the other options.
Got a job posting mass emailed to me today, here’s an excerpt:
“Our records show based on your resume, which was imported into our system recently that you are an experienced IT professional whose background may possibly align to the senior level position we have been retained to work on…” [Emphasis added by me.]
Wow, they didn’t even try to pretend that they read my resume or sent me a personal email, pretty ballsy, and of course the job had nothing to do with my skill set. It’s also hard to imagine any quality senior level candidates responding to such a faceless, generic email. To any recruiters who might be reading, this sort of email gets marked as SPAM.
