It's not blocked as much as it's made more and more difficult, because they can't hard block it (yet). So, the best advice, if you actually want advice and not just to bitch on the internet (it's fine if that's all you want, btw), is to organize. Organization is the single most powerful tool in political efforts, full stop. Examine the problem that affects voters in a given area and organize with the explicit goal of helping voters overcome those barriers. I'm not just talking about getting people to the polls, I'm talking demanding local policy changes, getting after state legislators, yelling at anyone who will (and many who won't) listen, organize and run local campaigns for city council or county supervisor. Those races can actually be competitive in deep red/blue areas, especially if locals know a particular person on their team is a shithead. Those positions also hold a shocking amount of power, and open up political communication channels that would otherwise be inaccessible. Idk if you're a communist, and I don't care, the American communists of the 1800s didn't just sit back and wait for the US to collapse, they got out there and faced likely being murdered to try and organize slaves to break up an unjust system. Get outside and stomp some grass if you want to see something different, bitching on the internet won't change anything.
