Did I just caused a global panic and send everyone fleeing to the hills? If not, then perhaps a people have enough sense not to believe every scare story on the internet.

On the other hand if officials are terrified that a single tweet will lead to a run on the banks, it implies that there is independent evidence that the bank is in trouble that will convince lazy skeptical internet users to get up from their comfy chairs and go out to withdraw cash.

Quick! Lock up the Guatemalan police, the superintendent of banks, and the president for using the Streisand effect to destroy the world's economy.

is a "Twit", surely

Guatemala is not a democracy. So why hasn't the United States dismissed its government from office, so that any murders that have taken place within it can be solved?

You've completely misread it. "Banrural is corrupt, so I withdrew all my money from them" is stating one's view and what one has done in response. He wrote in the imperative, encouraging others to withdraw cash from the bank with the goal of causing it's collapse. Granted, this is not providing "false or inaccurate information", nor does it directly "undermine confidence in a banking institution". Nevertheless, the intention is clearly to cause economic disruption, which is difficult to condone without extreme justification.

The extreme justification appears to be that the government is using the bank for money laundering and to hide other illegal activities while happily assassinating The Good People of the country who are trying to restore a political system worth living under or at least don't want to me made part of their crimes.
