Facebook’s TOS is actually more restrictive than Twitter:

We do our best to keep Facebook safe, but we cannot guarantee it. We need your help to keep Facebook safe, which includes the following commitments by you:
You will not post unauthorized commercial communications (such as spam) on Facebook.
You will not collect users’ content or information, or otherwise access Facebook, using automated means (such as harvesting bots, robots, spiders, or scrapers) without our prior permission.
You will not engage in unlawful multi-level marketing, such as a pyramid scheme, on Facebook.
You will not upload viruses or other malicious code.
You will not solicit login information or access an account belonging to someone else.
You will not bully, intimidate, or harass any user.
You will not post content that: is hate speech, threatening, or pornographic; incites violence; or contains nudity or graphic or gratuitous violence.
You will not develop or operate a third-party application containing alcohol-related, dating or other mature content (including advertisements) without appropriate age-based restrictions.
You will not use Facebook to do anything unlawful, misleading, malicious, or discriminatory.
You will not do anything that could disable, overburden, or impair the proper working or appearance of Facebook, such as a denial of service attack or interference with page rendering or other Facebook functionality.
You will not facilitate or encourage any violations of this Statement or our policies.

f you violate the letter or spirit of this Statement, or otherwise create risk or possible legal exposure for us, we can stop providing all or part of Facebook to you. We will notify you by email or at the next time you attempt to access your account. You may also delete your account or disable your application at any time. In all such cases, this Statement shall terminate, but the following provisions will still apply: 2.2, 2.4, 3-5, 9.3, and 14-18.

So, if he continues to use Facebook as a platform to harass, he can get banned from there as well.
