I'm running public web site based on Drupal. Drupal is GPL 2 or 3 licence. Of course I wrote custom code which interacts with Drupal code (modules). Can anybody write me an e-mail and ask for the source code of that my custom code? In other words, have I to publish that my code somewhere?
Claim to get my source code used GPL code

If your code is sitting on a web server and you are only serving web pages (or web services containing application data), then you are not distributing under the terms of the GPL 2 or GPL 3.  The Affero GPL is the one that requires you to release your source code if you are distributing web pages using software under that license.
