Answer 1

I don't know how many members there are.

Answer 2

I use bookmarklets. here's an example.

javascript:document.body.contentEditable = 'true'; document.designMode='on'; document.allowDeveloperTools = 'true'; void 0

to turn off (hopefully, Grammarly will edit the page after tho.)

javascript: document.body.contentEditable = 'false'; document.designMode = 'off'; void 0

and if you want, destroy a webpage.

javascript: var meh = document.getElementsByTagName("html"); var del = document.getElementsByTagName("body"); meh[0].removeChild(del[0]); var p = document.createElement("h1"); var txt = document.createTextNode("WOW MAN"); p.appendChild(txt); var div = document.createElement("body"); meh[0].appendChild(div); div.appendChild(p); void 0

also, this one does require you to load insecure content, so once you activate, don't put in personal stuff like passwords. (activate by pressing shield in top right corner, run script, (this refreshes the page) then press the bookmarklet again )

javascript:var i,s,ss=['http://kathack.com/js/kh.js','http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js'];for(i=0;i!=ss.length;i++){s=document.createElement('script');s.src=ss[i];document.body.appendChild(s);}void(0);

another version of the previous bookmarklet (b, arrows, space and esc)

javascript:var%20s%20=%20document.createElement('script');s.type='text/javascript';document.body.appendChild(s);s.src='http://www.websiteasteroids.com/asteroids.min.js';void(0);

and this makes all images images of Mr. Bieber. (might not work sometimes tho)

javascript:(function(){Array.prototype.slice.call(document.querySelectorAll('img')).map(function(el){el.src = '/assets/images/monkeyshine/bieber.jpg';});}())

(I only invented disabling content editing and webpage breaking.)

If you want, I can show you more.
