Jayjg is almost certainly employed by an organization dedicated to promoting and defending Israel, but I think it is likely that he has successfully completed his assignment with regard to Wikipedia: Israel's legitimate fear, early on in the history of Wikipedia, was that it would become a broadly accepted and anti-Israeli information source. This could be countered in either of two ways: first, by making it pro-Israeli rather than anti-Israeli; or second, by keeping Wikipedia from becoming a broadly accepted information source. And I think clause two has been accomplished.
Thing is, they did a terrible job of this. It took years, and has resulted in considerable embarrassment for Zionist groups such as CAMERA, simply by being suspected of supporting Jay and Co. whether such support was real or not.
If I had to do this, I would have just paid some starving Indian or Pakistani students to run proxy servers with scripts to auto-vandalize Wikipedia articles. Probably would have been cheaper and quicker. In all likelihood, Jay and his little butt-buddies decided to whitewash Israel all by themselves, then found out later that someone would support them.....they still act like amateurs!

In all likelihood, Jimbo made some sort of an exchange to promote and protect Jayjg.
This has been
suspected for a looong time.

how does Wikipedia keep another Jayjg from happening again?
Depends on the Arbcom. If the kosher boys figure out how to get a couple people onto Arbcom, they might have a chance. But their reputation is in tatters, and the Gaza attacks in January have done immeasurable harm to Israel's reputation. The usual "you're an antisemite, you're a Holocaust denier" crap is not very effective anymore*. So it would be a superhuman job.
Wanna make sure it doesn't happen again?
Encourage Arabs to edit en-wiki.
