Reading posts on other forums in Korat there seems to be abuse of the internet again. Somebody seems to have hacked into somebody else's Ebay account and attempted to change the contact information there.
From the Hot Summer 2009 we do know of an individual in Korat who cannot respect other people's privacy, collects information on them and even abuses this information he gained to hack into email and forum accounts. He even openly asked for and on top attempted to force people to help him spy on others.
Please ensure the safety of your passwords by not using any references to your personal history like wife's or kid's first name etc. Best are passwords of at least 8 characters and containing not only capital letters and numbers as well but also signs like $ or # in unexpected positions. Passwords should also be changed from time to time. If you're writing them down, use a code known to you like a false character in every third position or the like. And don't save your passwords on your PC for copying and pasting.
If you let your browser remember the passwords for your forum accounts, email accounts etc. make sure to set your browser to auto-update so it updates as early as possible when a bug has been found. And also do keep a virus and spyware program monitoring your system.
