Reasons for changing text information in the browser after loading the site page?

Question

Browsers

Hello!

The need to find out the reasons for the next situation that arose, related to the use of the Internet, was the reason for this question.

When repeatedly updating this page in the browser of the above smartphone, the replacement of the original text with the above text continued. When loading at the same time this profile page on a laptop and another smartphone, the above changes in the original text information did not occur. The functions of translation and tools for automatic conversion of posted text are not provided in this social network.

In connection with the described situation, I ask you to clarify whether, as a result of a technical or software failure, the text information downloaded from the site can change to another (other words), forming a text with a different meaning? Is there any reason to believe that this is the result of a deliberate intervention of the "human" factor?

Thanks to
