The bottom line is this is a great website for doing quick little projects and experiments with many many programming languages. Nothing fancy, just easy and quick to use. As for the WARNING by user GURBL I think it is rather unfair to say the least. There is ZERO evidence that any malware is sourced from this website. Simply using a proxy registration is not a crime and has many legitimate uses not the least of which is avoiding tons of unwanted sales calls and physical junkmail by unethical companies that scrape the registration lists to try and find new clients.
