Twitter is for the most part as toxic as you make it. You have to be willing to aggressively cull the people you follow, and there are always promoted Tweets in there possibly crapping over your nice timeline, but you can make a pretty nice place by being selective in who you follow.
Also, if you care at all what your "score" is on a social media site you will grow to hate it. No matter what the site is remind yourself it always has Who's Line rules: The points don't matter. If you're not an asshole they tend to just come naturally with time. If you're being hidden because your score is too low then you should probably step back and ask if you really want to be part of that community, since you seem to be so at odds with it.
