[Software Life] from applying to swearing

Today, someone suddenly scolded me on the Internet. I want everyone to help me analyze why.
Background
A few days ago, my company sent a recruitment information, and I left my QQ number in the recruitment information. So in the past few days, many people have asked me to join the job, hoping to apply for a job.

Cause
15:20:14 55 ** 1925
User 55 ** 1925 requests for authentication

Additional message: Apply

I agree, but the other party does not pass my authentication request. I don't think so. It's okay to talk about it like this. As a result, things began to develop.

Recruitment?

15:23:46 qingrun
Yes.

15:23:04 55 ** 1925
What is the salary?

15:24:13 qingrun
What are your values?

15:23:28 55 ** 1925
Look at you.

15:25:04 qingrun
Look at me. So you don't have to talk about it. I have no confidence in this point. Is there anything to talk about?

15:26:15 55 ** 1925
20 kper month
 

15:27:34 qingrun
I want to see your resume.

15:26:45 55 ** 1925
Do not show

15:27:53 qingrun
Haha. Goodbye.

15:27:06 55 ** 1925
I still don't know if you lied to your resume?

15:27:17 55 ** 1925
Goodbye

15:27:28 55 ** 1925
[SHIT]

15:28:28 qingrun
Is it useful to cheat your resume?

15:27:43 55 ** 1925
Of course, you are looking for a job.

15:28:56 qingrun
I'm looking for a job. Haha

15:28:07 xiufeng
No.

15:29:22 qingrun
If you don't trust my content, there is no need to talk about it.

At this time, I thought the other party was too unreasonable and I didn't want to appear in his QQ friends, so I threw him into the blacklist, that is, the information and the Dialogue title displayed above.

Result
After a while, I received a series of additional information.
15:45:54 55 ** 1925
User 55 ** 1925 requests for authentication

Additional message: Hello, apply

15:45:59 55 ** 1925
User 55 ** 1925 requests for authentication

Additional message: Hello, apply

15:46:04 55 ** 1925
User 55 ** 1925 requests for authentication

Additional message: Hello, apply

I didn't expect this person to apply for adding me as a friend. I sent a request for a long time and didn't see the other person going online. So I checked the other person's information and responded. Then, I dragged the person out of the blacklist and sent a request to the stranger.
The result is very unexpected:
15:59:23 55 ** 1925
User 55 ** 1925 rejected your authentication request

Additional message: Enter the reason for rejection and click "reject request" again.

Then, I received another message:

15:58:46 55 ** 1925
* You *, verify you **!
(I have compared several foul words above)
I immediately threw him into the blacklist, and I don't know how much he scolded. I understand that he later requested to join, just to scold me.

Summary
From recruitment to being scolded, today is a bit miserable. However, do you have to pay attention to such issues.
If you have no trust in each other, why should you apply? Recruitment and application can be discussed only when both parties have a certain degree of trust. If there is no basic trust, you will naturally be unable to continue talking about it. Why are you so angry that you have to swear? Is it good for you to swear? In fact, it does not matter to me. It is not worthwhile to hurt you.
Think about yourself. It seems that there is nothing too much to do. Besides asking a few questions about the treatment, there is no harm to others. I don't know if this person is excited today and needs someone to leak the fire.
From graduation to now, I have more than 400 or 500 people in recruitment negotiation (more than 5000 people in top three hundred recruitment), and I have been interviewed and applied for negotiation for less than 50 times, I believe that I will not even be able to make such negotiations hurt others, will it?
