I would have bothered to check, but I didn't know the people running the coin were untrustworthy and required constant vigilance, like you're saying.  Nobody told me, "If you have Gridcoin, you need to check regularly to see if you're being fucked out of your money."

So when people get the new Gridcoin, how often should they check online to see if their coins are being cancelled and made worthless?  Once a month? 

When I bought Gridcoin, there was no requirement to have Twitter.  They just took my bitcoins.  So, for the new Gridcoin, are you required to buy the coins with your Twitter account so you can be notified when the coins are obsolete?
