I think he meant deterring, putting off.
Best to my knowledge, ever since my website got published, Grybauskas made changes to how he conducts business and carries out procedures and surgeries. His is perfectly aware that majority of the patients who deal with him, have visited my website and know what to expect and how to act. For example I am aware of the fact that Grybauskas attempted to start providing treatment plans to new patients through his assistant, which I consider is totally unacceptable because it's not his assistant who will be doing the surgery, but Grybauskas and, therefore, it's Grybauskas who should be presenting the treatment plan. I suspect he does not like to answer inconvenient questions directly and wanted to avoid this by acting through his assistant. I placed a warning on my website that the treatment plan should always be provided personally by the surgeon who will actually carry out the surgery. This is crucial in preventing potential misunderstandings later.
If my website was shutdown, that would be the greatest gift for Grybauskas as he could return to his old ways and brainwashing tactics, but for now it's a big pain in the a** for him. So, yes - deterrence is the good term to use in my case.
