Mastodon also gives you multiple options to block content, accounts or even complete domains.
Since Mastodon is federated there are many servers. Choose the independently-operated service that meets your needs. Like email, you aren't limited to just members of that particular service. You can even install your own instance.
Mastodon posts are limited to 500 characters and intentionally do not have rich text. It's for microblogging :).
