Sorry, new users can only mention 2 users in a post

I would like to answer the question in my topic " Force default validation even without annotation
but am not allowed to do. I always get the message: “Sorry, new users can only mention 2 users in a post.” when trying to post my reply

You probably forgot to format your code properly, and annotations starting with @ are getting detected as user mentions.

Use the button with the symbols </> in the text editor in order to format code.

Alternatively, you can use markdown. Put a line with three backticks (```) before your code and another one after your code, like this:

```
public class MyCode {

@NotNull 
private String foo;

@NotNull 
private String bar;

@NotNull 
private String foobar;

}
```

Thanks, you were right. Fixed it, removed “@” from the constraints I wanted to name
