Massiv Vote Bot "Attack"

[leonor]

Hello,
currently one of my sites is getting a heavy vote bot "attack". I have already ReCaptcha 2 in my gateway page but this dosen't help.
I created a Cloudflare WAF rule for "a=in&u=", this blocked the last TWO hours two million visitors with a JS Challange.

Some one else have the same problem, maybe @cajkan ? What did you do when this happend to you?

Regards

What i recently did was added multiple captchas, on each refresh loads different captchas like: ReCaptcha, hCaptcha, VL Captcha etc...
