As the comments feature is also open to the general public, all comments at iModeler are automatically scaned for spam. This is required because of the known spam risks on the web. Usually the process is not noticeable, but on occasion the antispam program will retain the comment for a few minutes while it waits for more data.
As a general rule, a first-time comment from a non-registered visitor will also be retained for manual release by the admin.
Summarizing, there's no human intervention involved in the case you describe, and from what I can seen on my end, this has been resolved automatically. Happy posting!
