There are a lot of brokers!! How to filter out brokers

There's a characteristic of brokers writing here, lol.
 They're struggling not to get caught.
I would like to inform you about the characteristics of brokers’ posts.

1. Pretending to have researched several places over several months.
At first, he said, “I’m planning to have 000 surgery, and
 I’m looking into ㄱㄴㄷ, ㄹㅁㅂ, and ㅅㅇㅈ,” and asked
 me to write down several initial consonants and recommend them.
(Please don’t misunderstand that the above initials are examples in alphabetical order)
 Among them, the hospitals I want to promote are mixed together.

2. The hospital says it has decided and wants to promote it.
He said he was really looking forward to it
 even though he had not even had surgery yet,
 and mentioned the name of the hospital and the name of the director.
Why am I so excited to reveal the name of the hospital and director
 before the surgery
 ? 3. Before we knew it, surgery reviews were posted.
It exposes only the initial consonants very naturally, or
 secretly exposes
 the name of the hospital by clicking right below the title, or
 exposes it in a comment when someone asks.
4. There is an anonymous broker in the comments who always encourages it.
“Oh, I heard they’re good there”
 “I worked there too and I’m very satisfied”
 The first comment is that.
 Is that commenter also a broker? If you click on the ID to check
 , you cannot check other posts or comments
 because it is anonymous
 . So many brokers
 helped each other build it up over several months.
