Team, why don't you add the image captcha. Most sites are using it now a days. Your members will thank you for that!

They do have the google one on their other site, I guess they probably found this other one to be more effective. Works better for me anyway.

reCaptcha is annoying, it make me solve challenge 5 to 10 attempts and often get error. Very painful to start over again

Open with incognito tab. I had same problem for a long time. Incognito tab surelys solves problem
