Reddit: Post, clear, and delete

Reddit: Post, clear, and delete

For a year or so, I’ve been using a very useful and effective GreaseMonkey script, which deletes all of my Reddit posts.
Userscripts: Delete All Comments – it also deletes posts.

Reddit Enhancement Suite
Together with the Reddit Enhancement Suite option of auto scroll, clearing my history is achieved in a single click.

All good, but I came across a post on Reddit, by one of the mods, stating that deleted posts could still be read. That the last posted edit was cached away for reference by whomever was empowered to view them.

Not really an issue, but the aim of deleting posts is to erm delete them, so I have taken it on as a mission to either find a script that will edit over a post, then delete it, or build one of my own.

Now I’ve never built a GreaseMonkey script before, and I am not fully fluent in javascript, although I do understand it, and with a little trial and error I hope to be able to fudge my way through it.

Also there are a heap of sites available where I can request help, and this will be a great chance to get au fe with them… StackExchange, I am thinking of you.

Insert: Turns out I didn’t need to put my coding skills to the test, my google-fu came through 🙂
Here’s the new delete script: Reddit Secure Delete


So here’s the original code I’m using for starters, thanks to AVRPunk, let us play 🙂

// ==UserScript==
// @name delete all reddit comments
// @namespace http://blah
// @include http://www.reddit.com/user/*
// ==/UserScript==

location.href = “javascript:(” + function()
{

var deleted = 0;
var links = document.getElementsByTagName(“a”);
var i = 0;
var d = 0;

for (i = 0; i < links.length; i++)
{

var l = links[i];
if (l.href)
{
if (l.innerHTML == “delete”)
{
toggle(l);
d = 1;
}
if (d && (l.innerHTML == “yes”))
{
deleted++;

l.id=’xxx’+i;

var butter=”document.getElementById(‘xxx”+i+”‘)”;

var f=function(a)
{
hide_thing(a);
};

setTimeout(“change_state( “+butter+”, ‘del’, hide_thing)”, 1000*deleted);

d=0;
}
}

}

if(deleted>0)
{
setTimeout(“location.reload(true);”,1000*(deleted+1));
}

} + “)()”;

This solution is more than I could have dreamed of putting together with my limited skills, learn I will
