Seems viabtc changed order of entering captcha, allowing do it only after start new hours. Earlier was possible to do this in advance.
And they decreased the number of hourly free transactions to 20.
By the order of submission, ViaBTC supports 20 FREE acceleration chances per hour.
Edit:
I visited ViaBTC accelerator at 00:00 (UTC) and there was no remaining hourly free transaction.
I refreshed the page and after the second refresh, I got the following message from cloudflare.
The owner of this website (
www.viabtc.com) has banned you temporarily from accessing this website.
that happened to me too in other websites too. I think it is an automatic protection feature. when a website is visited (refreshed) multiple times from the same IP in a short time. that feature triggers and marks your activity as a bot activity and put a temporary ban for visiting that website.
they've probably added that as an effort to exclude as many Oridinal bots as possible. but these scammers will always find their way.
they probably decreased free transactions for the same reason too.
