On our site's server, once managed by someone who's no longer with us, there's a folder named "/manual/cache" which contains txt files named+like+this, mostly using pornographic-related keywords. The content is mainly spam-like gibberish.
My assumption on the matter is that it's somehow used to spam search engines, but I might be wrong, which is the reason of my question here.
Any idea what it might mean/contain?
As an additionnal note, the person's hiring period oddly correspond to the dates of the files, which seem to have automagically stopped being generated after the date we parted ways.
