[wp-hackers] Free themes have backlinks and backdoors inserted in code?

[DD32]

grepping for http:// wont help, they'll just obfuscate it.

Ways which it'd be possible to insert malicious links:
include()(remote url) / fopen() / JS / eval() / urldecode() / chr() /
. (string concat'ing 'h' . 'tt' . 'p')..

In short.. If you make a plugin, It'll be worked around by the
majority of those who insert the links..
