The pitfalls of automatically generated ads

I've been wondering why my Yahoo email account gets so many banner ads like the one pictured on the right.

After all, Yahoo and Google mail will automatically generate ads based on the content of the emails - and for the life of me I couldn't figure out what my emails included that would prompt ads for women looking for sugar daddies.

Then it hit me...my email box is filled of stuff with the word Elder in it! "Elder" must be one of the keywords that prompts this particular style of ad.

I guess I just have to get used to it...
