And I've always thought that theorbtwo's disclaimer is redundant. It's always been my assumption that all code under SoPW and all responses (to anything) is untested. I generally expect obfuscations, snippets and other prepared examples to have been tested beforehand. Outside of that no one should expect that the code is of any particular quality.

In fact, frequently I post code not because I expect the user to copy and paste it but that I expect the user to read it and write it down themselves. How else is the person asking the question supposed to learn things anyway if they just copy/paste prewritten code examples.
