Installed...

awesome job

A couple issues that arose right away with this mod:
1) members with < 15 posts are unable to report posts.
2) members with <15 posts are unable to quote posts containing links, images, or email addresses.

i would also like to use this hack but i only want to block urls, not images

thanks

Will this stop the spam bots that no longer use url tags? I see some of them post links that are not active as in you have to copy and paste them. So will this prevent those also? Can you rig this to work with signatures?

installed, but changed it to only work with under 1 post, just to stop spam.

i think it may work for those types of url because it blocks all of these:

($pagetext,'[url') or
($pagetext,'[URL') or
($pagetext,'www.') or
($pagetext,'@') or
($pagetext,'[at]')
($pagetext,'http://')))

you could add or remove others i suppose.

Actually I like this better:

If you would like a more advanced anti-spam mod please feel free to use the mod above. This one is very simply and has one objective, to filter URL's, Images and the like from new users. that is the goal of this modification and that is all that it does and ever will do. This is a very simple modification for people who don't want to configure settings e.t.c and it does the job it was created for.

Does this work with 3.7.1?
