Will Facebook get banned for manipulating DOM elements?

Question

JavaScript

From an ordinary account on manually opened pages on Facebook (at the same time no more than 3-4 pages), using JavaScript and the Tampermonkey browser extension, I perform various elementary manipulations with DOM elements. But only on the current pages, my script does not open any links, it does not climb anywhere further, and it does not collect any other information other than what is already on the page. The browser console reads: "[Violation] Added synchronous DOM mutation listener to a 'DOMSubtreeModified' event. Consider using MutationObserver to make the page more responsive." As I understand it, Facebook monitors my manipulations and they are not a secret for him. What is the probability that sooner or later he will get tired of watching these actions and I will be banned? And if the probability is high - where is the line in such manipulations,

Answer 1

Won't ban

Answer 2

If you are sure Facebook is following you so much and gives you this error as a warning, then it’s better not to think anything extra with the tab open. You never know.
