Need To Find A Twitter Dataset That Has Random Tweets Over Several Years

Hello,

I’m conducting an independent research project surveying the prevalance of hate speech in Twitter throughout the years, seeing if the ratio of hate/non-hate has increased over time and if the rise is correlated to any other long-term trends (such as the popularity of Twitter or political climate). For that, I need data over several years of Twitter so I can link longitudinal trends to hate speech data throughout time. In addition, I would want to get a randomized sample so the study has less chance for bias or error.

So, are there any publicly accessible Twitter datasets that has data over several years without any content filters? And if not, what should I do to get longitudinal data for this study?
