A friend of mine recently approached me about paying me to write some software that would automatically login into various websites to automatically check if his balances for things like cell phone minutes, checking accounts, credit card accounts are running low. This software would either email him or call him if anything was running low. This seems like it would be easy enough to do, as I have done similiar things with WWW::Mechanize before. My main concern is if there are any legal issues with automatically logging into websites, especially if it is for profit. Has anyone had any experience with this?
