It means essentially removing myself from the internet. No public social media and hiring a company to get myself (i.e., address and phone number) removed from public data brokers (you can do it yourself, but it means hundreds of unique forms to fill out). You seem to be hung up on "obscenities" but yes you are correct, it's not just obscenities... there are a lot of varieties of harassment. Following someone around and shouting anything at them is likely harassment IRL, but it seems less clear online when you can't conclusively determine if anonymous accounts are the same person.
