Could the ‘style’ of the community be changed to include some small graphic or suchlike in order to highlight where someone has embedded a link in the text. Whilst the change of color may stand out for a large piece of text, it's becoming more common for spammers to embed links on a single bit of punctuation which can make it almost impossible to spot. e.g.
(that link will only be visible to moderators/admin)
So, whilst the text appears to be relevant to the community, the spammer (or AI bot, as a lot of these read like they've been generated from the question) has embedded a link on the full stop near the end.
With an obvious graphic (perhaps a superscripted link image) next to the link it would make it easier for the moderators to spot these attempts - although we're already aware of this type of spam it's time consuming to find them.
