Frankly, anyone trying to contribute intelligently in this kind of forum, while using a phone, is asking for trouble. If you aren't willing to proofread carefully BEFORE you post, you can expect to be blasted for your poor spelling, wacky ideas, disjointed thoughts, unsupported assertions, and heretical statements.
It's kind of like driving a car. You need to pay attention, because if you miss the speed limit sign, it's still your fault for speeding. You ARE responsible and accountable for what you post, whether you like it or not. Sure, you can apologize, restate, clarify, and so on, but in the end, you own what you posted, and if reflects on you. Therefore, be cautious.
As an aside, a five-minute editing window in real life would be wonderful! Five minutes to edit a post is generous.
