: I've noticed a bizarre (malicious?) behavior in my website logs My website logs spit out "invalid content" messages -- they typically occur when someone types in a wrong hyperlink or a page

A possibility is that these hits are made through links that people have added to their blogs/sites or shared with others using email, social networks etc.

It's happening to me all the time. They try to add a link to their website, but they do not make the copy paste correctly or they add extra characters or even delete some of them (accidental/mistaken keystrokes).

That's why some of the last characters are missing or url variations appear.

Suggestion

If you load the page based on post's id for example 1048, try to redirect to the correct slug if the slug is not the correct one

Also if the post's id does not exists but the slug exists, redirect to the correct url again.

If the given post's id is invalid or does not exist, and also the slug does not exists, try to find the most relevant url to redirect to, or display an error 404/410 with the urls that are the most relevant, so that the visitor can click and be redirected to the article that he wanted to read.
