Step 1: First of all, the first method is to block the information sent by them, log in to QQ, then find his QQ number, then right-click his QQ name and click "Block this person's information" in the setting permissions.
Step 2: If his message is blocked, but we can still receive his message, we will do the next step, open a chat window with him, and then click the inverted triangle symbol behind Tian Zi at the top of the chat window.
Step 3: In the pop-up options, we first click "Delete Friend" to delete him.
Step 4: In the confirmation window that pops up, we click OK.
Step 5: After deletion, we click on the inverted triangle behind Tian Zi at the top of the chat window. In the pop-up options, we click "Report".
Step 6: In the report window that opens, we click "Spam Harassment".
Step 7: Continue to click on "Spam Advertisement".
Step 8: Check "Move him to the blacklist", and then click the "Submit" option in the lower right corner of the setting window.
Step 9: After completing all the reporting steps, Tencent will review our reporting information, and then we will receive their handling. Under normal circumstances, their enterprise QQ will be restricted from logging in or being disabled, so that we can play the role of shielding the information they send. This is the most effective method at present.
Precautions:
If we block his news, then we need to delete our friends first, and then report it, because it's no use blacking out corporate QQ.
I'm glad to answer your questions and hope to adopt them!
