Hi there,

In found the invisible recaptcha plugin which works like a charm with Contact Form 7.
Check this out

Hi,

I’ve had lots of troubles when suddenly I’ve received hundreds of emails from my MailPoet plugin “please confirm your email address … “
The bots were trying to sign up for the newsletter again and again with my own email address.
WangGuard did not stop any of them.

The only plugin that was able to properly handle this was Goodbye Captcha – https://www.ads-software.com/plugins/goodbye-captcha
They have an excellent reporting system so… I’ve seen in the reports that my own email address was used for sign up.
It works fantastic and… for 5 bucks… it is totally worth it.

On the other hand, a captcha solution is not suitable at all for subscription forms and WPBruiser(Goodbye Captcha) integrates with lots of plugins for free so… instead of reinventing the wheel why don’t you contact them and probably you guys will sort it out to have this integration free for everybody. By adding a captcha on our forms the conversion rate will drastically drop.

Hi Yorman,
Thanks for your prompt response which totally makes sense but I am still confused here with my first question.
To be more clear:

For Apache you recommend to whitelist:

2a02:fe80::/29
192.88.134.0/23
185.93.228.0/22
192.124.249.0/24

For Nginx you recommend to whitelist:

192.88.134.0/23;
185.93.228.0/22;
66.248.200.0/22;
2a02:fe80::/29;

My question is: Why there are different ranges for different web servers?
As I can see the range 192.124.249.0/24 must be whitelisted ONLY for Apache and the range 66.248.200.0/22 must be whitelisted ONLY for NGinx.
