I don't see anything wrong with the post in relation to the (ISC)2 code of ethics. It's just a suggestion that might help with your studies, not an advertisement for anyone. I haven't mentioned anything specific about the exam content, just a reference to additional sources you can use alongside the self-paced training from (ISC)2.
It's important to note that the exam agreement clearly states not to disclose the content of the examination. However, it doesn't mention any restrictions on sharing study materials that can help to gain a better understanding of the self-paced training.
If you want to feel more assured, you can check out the full exam agreement at this link

If I've done something against the rules or missed anything, please review the (ISC)2 code of ethics. The code includes the following principles:
1. Protect society, public trust, and the infrastructure.
2. Behave with honor, honesty, fairness, responsibility, and legality.
3. Provide diligent and competent service.
4. Advance and safeguard the profession.
😇 Godbless.
