Should politicians be allowed to block their constituents on social media?

I’m not sure when it started happening but many politicians have begun blocking people who disagree with their ideas. Now the courts are saying that it is illegal as it blocks freedom of speech. These politicians claim they are blocking harassment. Some states are telling their politicians that they have to unblock those people or they will have to cover the cost of any lawsuit that results from the blocking. So, should politicians be allowed to block their constituents who don’t agree with them or do they need to face the consequences of their decisions???
