content: There are fairly easy ways around a filter that look like garbage to the computer and a human but are oddly readable. For example:  Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteers be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.  That is a garbled mess when looked at from a computer, when looked at by a human it is a mess but readable without as much difficulty as you would expect based on the way the letters are done.
