Comment Block Spam
Permalink
Hello All
I have a client that uses the comment block standard on a page type viewed often by its guest.
We are having issues with the comments section being spammed.
Does anyone have a fix for this issue, or are able to suggest a fix.
Thanks for your help

If you want to improve the block yourself, I'd suggest the following:
- IP check vs IP blacklist
- Email domain check vs user defined domain blacklist
- User and server side form fields validation
- Domain DNS check for existing record
- Captcha validation
- Cross site request forgery protection (C5 token check)
- Form inputs sanitizing
- Limit on submission frequency

Disallow any post that includes a hyperlink.
1. Use either C5 core Captcha or install the reCAPTCHA addon
2. Limit frequency of comment submissions from same IP
3. Better allow comments only from registered users - this will stop 99.9% of the spam
