The first way that we can decrease the spam problem is by using a ''blacklist'' filtering approach. There is a widely used MediaWiki extension called [http://www.mediawiki.org/wiki/Extension:SpamBlacklist Spam Blacklist] that checks instances of URLs in new posts against a shared blacklist. If a match is found, posting is prevented.

== List of anti-spam features ==
 
 
As of 2014-03-16, here are the anti-spam features installed and enabled on OpenCircuits:
 
 
built-in anti-spam features:
 
* GroupPermissions is set so no one can edit unless they are logged in (sorry, anonymous users)
 
* EmailConfirmToEdit is currently enabled
 
* [http://www.mediawiki.org/wiki/Manual:Combating_spam#DNSBL EnableDnsBlacklist]
 
* [https://www.mediawiki.org/wiki/Manual:Autoconfirmed_users Autoconfirmed users] have some [https://www.mediawiki.org/wiki/Manual:$wgRateLimits RateLimits] set up; how can I tell if it's set too high or too low?
 
 
anti-spam extensions:
 
* [https://www.mediawiki.org/wiki/Extension:ConfirmEdit ConfirmEdit] (<s>reCaptcha</s> QuestyCaptcha)
 
* [https://www.mediawiki.org/wiki/Nuke Nuke]
 
* [https://www.mediawiki.org/wiki/Extension:SpamBlacklist SpamBlacklist] [[MediaWiki:Spam-blacklist|OpenCircuits SpamBlacklist Page]]
 
* [https://www.mediawiki.org/wiki/Checkuser CheckUser]
 
 
other extensions:
 
* Gadgets
 
* Math
 
* ParserFunctions
 
* Renameuser
 
* Vector
 
* WikiEditor
 
 
other built-in features:
 
* UseInstantCommons is enabled (so you can use pictures of electronics on http://commons.wikimedia.org without re-uploading them)
 
 
=== EmailConfirmToEdit ===
 
 
The EmailConfirmToEdit seems to work for people who have email addresses at:
 
* gmail.com
 
* mailismagic.com
 
 
Alas, it appears that "EmailConfirmToEdit" doesn't work for people who use an email address at "outlook.com" or "hotmail.com", because Outlook and Hotmail are blocking email from us.
 
* outlook.com
 
* hotmail.com
 
* live.com
 
* comcast.net
 
I see we're not the only ones who [https://discussion.dreamhost.com/thread-45444.html can't send email to Hotmail].
 
 
What can we do to allow those people to make good edits,
 
without opening the floodgates to spammers?

=== Delayed confirmation ===
 
 
On 2014-03-22,
 
I tweaked the settings such that no one is allowed to edit until
 
(1) a person creates an account with an email address,
 
(2) the email confirmation confirms a valid email address, and
 
(3) the sysops confirm the account, usually within 24 hours.
