I'm not really proficient in using mysql/php, and in my website I noticed that either people/spambots are inputing suspicious words into my mysql parameter things (not sure what to call them).

For example, I use mysite.com/avatars.php?series=seriesName to sort my avatars. But I see people entering urls of a completely different website after the equal sign. The URLs are really weird ones, so I think they're either porn websites or some other unsavory site. I'm not about to visit them and find out.

When I try entering a random thing after the equal sign, or a website url after the equal sing, nothing seems to happen. Except it returns an empty page. So is this something I should worry about?
