Brokers don't like clients staying on demo accounts for too long?

Hello Master, I am still a newbie in forex trading. I use a Demo Account to learn trading. At first, I registered for a demo account at icmarkets, but it got MC (I assume this means "Mastercard"?), so I created another one, and it got MC again, and so on, until I had 25 demo accounts. The broker said that 25 demo accounts are too many and I can't create another demo account. As a newbie, I was curious because how can I not be profitable. Then I registered with Hotforex, created a demo account, and got MC up to 10 demo accounts on MT5. Then Hotforex informed me that the demo account has exceeded the limit.
Master, I want to ask, do brokers not like it when newbie clients stay too long on demo accounts? I want to find a new broker to practice on a demo account. Two brokers have stopped providing demo account services already, even though newbies need a testing tool on the demo account. Anyway, I'm determined to keep learning until I can consistently profit.
