The crackdown has begun, and I have already fallen victim to ( as shown in the picture ).

My experience is nothing unusual, here's what happened:
A long-time friend in real life asked me to buy some U for him. He's not a stranger I just added; we've been friends for many years, but we don't contact each other much during our free time. He directly transferred the money to me, and then, as shown in the picture, it got locked.

You may have also seen the news that on November 17th, the Security Center issued an announcement clearly stating that it will crack down on pyramid schemes and fraudulent activities that falsely use the terms "blockchain" and "virtual currency".

I didn't expect the execution to be so swift and forceful. Just a few days after the announcement, many virtual currency chat groups were directly banned without any warning—what everyone commonly refers to as not having a "red exclamation mark" warning. Many group administrators were also dealt with, with bans ranging from 1 day to 30 days, and some even received permanent bans.

So how can you protect your account security? Here are a few reminders to keep in mind:

First, try to avoid discussing topics related to virtual currency in here recently. Especially slang terms like "B circle", "oil", and "big pie", which can easily trigger the system's keyword monitoring. Most of the current monitoring is executed automatically by bots, and once triggered, the processing is quick.

Second, be cautious when sharing links and QR codes. Especially the links or invitation codes for exchanges, the behavior of "leading orders" (recommending buying and selling) in groups carries a high risk, so it is best to avoid it.

Third, pay attention to social behavior. Do not frequently add friends or make transfers within a short period of time, as these actions may also attract the system's attention.

If you have a group of friends, it might be a good idea to temporarily shift the topic to other aspects of life; safety first.
In short, this time it was serious. If you have added some less active or no longer useful groups, leaving them is also a safe way to avoid "collateral damage."
Be careful, it never hurts.
