I've got 3 tools and 2 extensions you guys may like.

First, the extensions.

The first extension is called TitleBlacklist. It's a list of words or letters you cannot use while asking questions. I do not know if it's enabled by default, but here's a list of words we have at Wikianswers:

 #<!-- leave this line exactly as it is --> <pre> 

# This is a list of 'blacklist' titles.  Changes here will affect all page titles on this Wikia only.
#
# Syntax:
#    - Everything from a "#" character to the end of the line is a comment
#    - Every non-blank line is a regex fragment which will match page names
#    - Be default, all regex is case insensitive; this may be removed by putting
#      <casesensitive> after the expression
# see also MediaWiki:BadWords

###Well, all questions are required to be worded like questions...###
^[^a-z]*$
^[^aeiou]*$

###NO CAPSLOCK####
^[A-Z0-9_]*$ <casesensitive>

###IPs###
[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}

###SINGLE CHARACTERS WHICH SHOULDN'T APPEAR EVEN ONCE###
[Щбильгن¿•?■]

###Non-English words and characters###

Another extension is DPL. It is used to find questions from a regex.

Next: Tools

Annihiliate.js This tool will delete AND protect tons of questions from a list of pages. It is useful with DPL.

Gadget-HotCat.js This tool is used to manage easier categories on pages. One click add, one click remove, easy as that!

FastDeleteProtect.js This tool makes buttons near the edit button to delete AND protect questions.

To use with FastDeleteProtect:

Those are the buttons to add with the import (You can customize them, ofc):

// Variables (Auto delete & delete and protect)
var fdButtons = [];
fdButtons[fdButtons.length] = {
        'summary': 'Vandalism',
        'label': 'V'
};
fdButtons[fdButtons.length] = {
	'summary': 'Spam',
	'label': 'S'
};
fdButtons[fdButtons.length] = {
	'summary': 'Junk',
	'label': 'J'
};
fdButtons[fdButtons.length] = {
	'summary': 'Opinion',
	'label': 'O'
};
fdButtons[fdButtons.length] = {
	'summary': 'Non-English',
	'label': 'Ѭ'
};
fdButtons[fdButtons.length] = {
	'summary': 'Not a question',
	'label': 'NQ'
};
fdButtons[fdButtons.length] = {
	'summary': 'Homework',
	'label': 'HW'
};
fdButtons[fdButtons.length] = {
	'summary': 'Clean-up',
	'label': 'C↑'
};
fdButtons[fdButtons.length] = {
	'summary': 'Too broad/not enough detail',
	'label': 'B'
};
fdButtons[fdButtons.length] = {
        'summary': 'Unused',
        'label': 'U'
};
fdButtons[fdButtons.length] = {
	'summary': 'Violation of Wikias terms of use (pornography, advertisement, etc.)',
	'label': 'ToU'
};
 
// Import for Delete & Delete and Protect buttons
if (wgNamespaceNumber == 0) {
    importScriptPage('User:The Mol Man/FastDeleteProtect.js', 'a');
    } else {
        importScriptPage('FastDelete/code.js', 'dev');
};

Thanks! Hope this is useful!
