Coco Chat Site (Paywall Incentive)

Hello, I have always chatted on Coco Chat, but for the past two days when I try to connect, I'm told too many people are using your IP, please purchase a premium package...
It's true that I tended to change my username for a long time, but now they are forcing me to pay, I wrote to ask why and how to get back online to chat, but I haven't received any email response, no explanation, I was not rude to anyone, I didn't do anything serious (no cam, no inappropriate gestures, no insults, etc.)
In short, they're asking me to pay, isn't that an abusive way to force people to pay? These methods seem incorrect on their part; usually, bans are justified with reasons, but that's not the case here.
They claim to be a free site, but I seriously doubt it now. If you have been treated this way, please share your experiences, because until now, I still don't know why I can no longer access the site to chat. Thank you in advance.
