This won't be a post related to programming. However I find this useful to fight spam with GMail.
I know most of the spam contain some specific words so I tried using google's search engine inside GMail to simplify this horrible task. Here is what I copy-paste to the GMail search bar:
in:spam pharmacy | cialis | viagra | replica | rep1ica | buy | cird | bedroom | watches | pills
The OR operator works great and then I can delete the messages that meet that criteria without worrying (well, I do worry a little but less than deleting them without any filter at all).
I can say that 60% to 80% of spam I get contain one of those words.
