For a long time before the beginning of this year, there was almost no case of advertising accounts being kicked, but since April and May, this situation has become more and more frequent.
Two months ago, a few accounts disappeared occasionally, but the proportion was less than 10%, so I didn't care. A few weeks later, accounts were kicked on a large scale, and all account administrators in the same group were kicked at the same time.
There is a strange situation. After the account administrator is kicked, the account still exists in the BM with the same account management authority, but the authorization number with the account management authority loses the management authority. Generally speaking, even if you are the administrator of the advertising account, you cannot perform the above operations without BM authority. However, in the end, these BMs did not survive and were kicked out.
Although there are many guesses about the reasons why accounts have been kicked in batches, there is still nothing we can do to prevent accounts that have been kicked. The common feature of kicked accounts is that they all have an administrator who cannot be removed.
However, if someone wants to move your advertising account, it can only be done through this administrator. So now, there are some risks in using this advertising account. You should consider whether to use it or not and how to use it.
