如何举报这些代注册抽签的公司？

看到一个某个帖子
突然想起来注册期间邮箱收到过几封奇怪的说可以帮你注册h1b的邮件 大概三四封
现在非常好奇这些单位是不是特意在那段时间注册然后帮抽签的公司？
如果是 只知道他们的公司名称 是否可以举报？如何举报？

I would like to inform you that GP Technologies LLC (an E-Verified company) is sponsoring H1B for this cap season i.e. March 2021. Consultants who are willing to get registered from our company can send me below mentioned documents, so that I can have it in my database and once I receive your details, I will be contacting you during registering.
