There is a question for Google experts

The situation is as follows: I turn on the computer and I can not log into my Google account, asks to enter a phone number. No explanation, nothing. Entered the number, came the confirmation code, entered the code, the account has become available.
Actually, what was embarrassing besides the fact: Where is the guarantee that this is my phone? and if the enemies would have entered their?

After some time, I find that my working documents (a quotation to the customer and the calculation of the cost of the work, shared by reference to the reading) are closed with the wording:

The published version of this object is marked as inappropriate, sharing is not possible. Request for review.

Clicking on the request for review link leads me to a page with this content:

There was an error processing your request.

(very much like Microsoft, by the way).

Actually the purpose of the post: to warn about an unpleasant illness, and it is possible to find out what it is? what are the possible reasons? If anyone came across or knows why this can happen - please contact me and lichku
