keyword spam protection

[Chadi]

I used to use a mod for 3.8 called Check4Spam which is not in mod graveyard unfortunately. I'm looking for something similar for 4.2.0

I need these functions:

- no links / images unless minimum forum post count
- usergroup set permissions (enable/disable feature per usergroup)
- no images unless minimum post count
- spam keyword block (such as [dot], [img, .com, etc for those who try to work around the filter backend)
- keyword whitelist

Thanks.
