We use recapatcha here, so we do not get so many spammers. On the old site, we were getting around 50 spammers a day.
If you cannot understand what the recaptcha is saying, you can select "image", instead. That selection is at the bottom of the captcha box.
I have used both.
Sometimes, it took me 15 attempts, to get the image to work.
I know this is frustrating. We are working on doing the best we can, to make this website secure.
Once you get logged in, you should not be asked to select images or video, for a while.
I hope this helps. I apologize for the frustation.
