Plot Outlines and Summaries that end with a semicolon?

Should Plot Outlines and Summaries that end with a semicolon be accepted? There are a number of punctuation and other corrections that the submission system applies when checking user submitted data. I noticed a large number of outlines and summaries on daytime talk show episodes that end with a semicolon, which seems odd to me. Examples: https://www.imdb.com/title/tt0123366/episodes/?year=2025 https://www.imdb.com/title/tt10827252/episodes/?year=2025 What is the IMDb policy for ending Outlines and Summaries with a semicolon?
