will remove some behaviour specific to account API keys are from

@LucieGueuning I have tested a change of Twitter API keys locally, and am just applying that change now to make it a bit more neutral, however even with that change I was still picking up a lot of petabencana tweets, simply because the bot sends lots of replies with the word "flood" in it, in fact actually more than it should, due to urbanriskmap/cognicity-cards#13
I am just about to push a fix that excludes petabencana from the search results. The only gotcha is that will miss the informative tweets that petabencana operators put out in English.
