Keep in mind that Twitter is just one more facet of the free-for-all known as the Internet. There are no real rules in terms of how to use it (except perhaps, the law, and we’re still sorting that out), so at the end of the day, people are free to do what they want. And they will. Some use Twitter for good — to promote fair elections — while others will harness it for self-profit — to promote brands and advertisements. They will annoy you, and you will annoy them. Take a step back, breathe, and relax — people are going to do as they please and there’s nothing you can do about it. There’s no sense in trying to change them. Just go with the flow, for better or for worse.
