//words.push(block);
//For example, if you wanted to ignore SSBB topics, you would add the following line (without the slashes):
//words.push("SSBB");
//For multiple words, use multiple lines.
//The blocked words are not case sensitive.
//Add them below this line

//Add blocked words above this line ^^
