what's the reason my account was blocked? i can't contact any support, only try registered again from different mail, I read the message which have only 'hello', and nothing explain what's happen?
If your account it very new, discourse has new user limits (not set by LE).
It usually tells you what limit has been reached.
Do you have a picture of the error?
Without seeing what you are seeing, it is very difficult to even understand what is happening.
I concur with @rg305.
What kind of account are you meaning? A Let's Encrypt Community account? A Let's Encrypt ACME account?
Let's Encrypt Community account, with no explanation
I've contacted someone on staff who is looking into this.
I wasn't able to find a detailed reason in our Discourse logs, or a copy of the post, but it looks like your first post had been detected as spam for some reason.
I've unblocked your e-mail address, so you should be able to register again. Sorry about the trouble!
