As if posting from a mobile device somehow prevents you from using paragraphs and punctuation? Give me a break. You either can't be bothered, which means you're not worth interacting with; or you had to repeat at least a high school English class or two growing up. Either way you need to stop blaming your fucking phone.
There's not a good reason for anyone to blame their phone anymore, but mobile formatting used to be a real issue. Different apps required different amounts of blank lines to actually make a separate paragraph, so people often got giant blocks of text instead on accident, or paragraphs with two lines in between them.
