1, if you don't contact frequently, it means you are not familiar. Deleting the other party will not care or be sad;
2. My friend can delete me, and I can also delete him;
3. Wechat doesn't need to care about deleting friends, but it cares more about deleting each other in life. I don't think Tencent's open one-way friend detection patent is a new technology, but Tencent may have new functions. There was a related one-way friend detection third-party software before. Now Tencent has applied for a patent, but it only uses its own data on Tencent WeChat platform to develop this function. At the same time, it is convenient for users to use this function. Just click on the relevant options, you can display the deletion of friends, so that many people can know that they have been deleted by others without looking for third-party software, and they don't have to be little fools who don't know about it.
Although I don't care that friends who don't contact me often delete me, I also want to know whether I was deleted by the other party, so that I can re-examine my relationship with unfamiliar friends, instead of adding more friends who can continue to be friends with each other, and also reduce the trouble caused by two unfamiliar people.
As a user, I think the advantages of this technology outweigh the disadvantages, which can allow more people who use WeChat users to further screen the relationship between WeChat friends, instead of becoming strangers who don't chat with each other often after adding friends. But applying for a patent needs to be considered. After all, after applying for a patent, others will also develop and use it, which is very likely to be suspected of infringement. However, technology is partially open, and once it is restricted, it is difficult to produce new technological ideas.
And the development of this function can be large or small. After using WeChat for so many years, without this function, I can't see it being deleted by unfamiliar friends. Many people don't care much about deleting friends. More is affection, money, affection and so on. Use WeChat chat as evidence, so that even if it is deleted by the other party, it is more important to keep the previous chat record. Delete things that are just a moment, whether you care or not.
