There can be few more important hobbies than protecting Israel's reputation on-line (and elsewhere, I know) because some samples of the worst Internet postings that I've come across include these horrors:

A Star Of David, in colour yet, likened to a spider.
Blaming Israel for the Middle East war - a regular, that.
A fake Shul with abusive Rabbis running it.
Reading the word Zionist used as an insult.
Jews assumed to run the media/world - where? how?

...need I go on? :)

Doing searches out of curiousity using the words Jew and Israel has led me onto this hobby, so though I know robust use of the Internet (both Google and Youtube) is a newish phenomenon, please join me.

Thank you, because the rubbish currently on-line finds its way to debates off-line in the public arena, sadly, I see this frequently as I don't live in particularly well-populated Jewish area.
