I was smiling while typing my meta description but I really am not in the mood!

I start getting medication spam (well, medications now but I know the rest should soon knock at the door) on a site products support board

I am now playing with banning IPs and emails
However it is like a band-aid on a wooden leg

Any prevention method (phpBB2 forum)

Thanks to share your experience

Regards

Henry

I have a partial idea:
I can transform via XL, CSV my email anti spam list in a SQL doc and inject it in the forum banned emails list

Now I do not have an IP listing of banned IP

Has anyone ever published such a “one size fits all” banned IP list of well know IP spammers?

Hi Henry,

Better that we move this thread over to the forum forum.

1. Go members only.

2. phpBB2 is very easy to modify. Here's an idea for you : edit viewtopic.php so that the "MakeClickable" function in functions.php is not called on any post by a member with, say, less than 10 posts.

3. Use your word ban list on URL's frequently spamming you. The combination of that and #2 above will at least make life very tricky for them.

4. This might surprise you, but write to the spammer. I've had excellent success doing that. Generally you get a "LOL, ok no problem" response and that will be that.

Glad you found your way over here, Henry0!

If the spam is automated (bot spam), be sure you are doing image verification on new registrations.

Image auth is often referred to as captcha. I'm not being a smart*ss, I just thought that you might find more ready-made phpbb software by querying Google for that term. Captchas work well to prevent comment spam on my Drupal site. There are a couple of ways to crack captchas but none of them is easy to implement. Unless your forum pages have PR10, they are a pretty reliable spam prevention.
