Spamlists and WordPress

Tags: , , , ,

I’ve been getting dozens of e-mails with spam posts to this blog and it’s become far to annoying to ignore any further!  I’ve been using WordPress’s integrated blacklist tool, but it’s time consuming to maintain and only protects against past threats.  I took a look at the database and I’ve managed to collect over 3,000 spam comments that take up more than 20 mbs of database space…which is quite a lot IMO.

In the past the best prevention I’ve found against spammers is to use spam lists.  One I like in particular is FSpamlist.com.  You have to sign-up to get an API key, but after that using it is very straight forward.   Stop Forum Spam is a big one too, you don’t need an API key to check for spammers so it was even easier to add.  I put a simple WordPress plugin together to integrate the lists with my blog.

I’m currently not planning on submitting it to the WordPress plugins directory or anything like that, but you want to try it out too you just save the code as “spamlist.php” add it to a “spamlist” folder in your plug-ins directory and then it ought to show up in your admin where you can active it.

It’s currently not set to report the spam that it blocks in any way…I’m not sure if I want it to or not.  I’m currently looking at over 3k of spam comments that are just sitting around taking up room in my database, but at the same time I don’t want to get any legitimate posters blocked without anyway of knowing.  Anyways, I’m going to test it out for now and see how it goes :)

Spam Words

Tags: , ,

This is a very simple spam prevention mod for phpBB2.  The idea is that you define specific words that come up often in spam and it will block messages containing those words.

There is already a “spam words” mod out there, but with this mod you don’t need to make any database changes and you can set how many times the words need to be matched before blocking the message as spam.  Although, there isn’t an admin panel to go with this mod so settings need to be changed in the code.

Features:

  • Checks if a post includes any designated spam words
  • Set how many times those words need to be found to mark as spam
  • Set how many posts a user needs to have their post checked
  • PM a designated account with details about the post
