I know peoples accounts have been cracked whitch means order people have your details and have been taking your stuff if it says You have logged in from another location change your password fast guys this is a big thing
The Suggestions section is usually used to give ideas for changes or additions to the server, not password changes :p This happened a while ago, and Mojang warned about it. Regular password changes are always a good thing, cracked account or no. As a precaution for keyloggers that can get your passwords to accounts, don't click on suspicious links, even from people you trust, because they too could have been keylogged. I would suggest moving this to off-topic or another section, not suggestions.
You need to be dumb enough to download something and then run it. Clicking on things is generally safe unless you click on something from @Camel ;) then you're sad.
Once Again KeyLoggers are used to Monitor Key strokes and even if some one Scraped the Mv server for all usernames u would have to have the stupidest password ever to lose your account Useless Thread
My alt was probably not cracked but maybe the poor soul wanted his account back and complained to mojang.
