GitLab leverages Akismet to protect against spam. Currently GitLab uses Akismet to prevent users who are not members of a project from creating spam via the GitLab API. Detected spam will be rejected, and an entry in the "Spam Log" section in the Admin page will be created.
Privacy note: GitLab submits the user's IP and user agent to Akismet. Note that adding a user to a project will disable the Akismet check and prevent this from happening.
