Hi,
As for the Spam:
Unfortunately, none of the captcha plugin guarantees 100% spam security.
1) Spam may come from the forms without captcha – please check your site and all the forms on it.
2) Please check if captcha works and blocks submission if entered incorrectly.
3) We can recommend you to increase captcha complexity on the settings page and update to the recent version if you haven’t done it yet.
4) Maybe our plugin Limit Attempts (https://www.ads-software.com/plugins/limit-attempts/) will help – With this plugin, you can limit user’s attempts to log in to your website and, consequently, block the user for a certain period of time.
As for the Nag-Screen:
You can close banners with ads. When you close any of the banners, your browser creates special cookies and they are not supposed to be displayed after that. So it is possible that cookies are disabled in your browser or you just clear them. It works if :
– you keep cookies
– you always use the same browser (on the same computer).
