Here in internet forums the only perception people have of you is based on what and how you write or put together a post. You do yourself no favors by just throwing a wall of text out there with no concerns for spelling, grammar, punctuation, paragraphs etc. It makes a difficult read for everyone who was initially interested. Many will just skip over a poorly executed post and not make any useful comment.
The bottom line is you lose the benefit of having all these knowledgeable people around and you won't be taken very seriously. You will have made it very difficult for people to offer advice to help resolve the problems you are experiencing.
In some cases there are disabilities and language barriers to deal with and that can be taken into account by the readers if they are made aware of it. How fast someone can type, text or even send Morse code doesn't matter much if the end product is not understandable. Making a longer post using a phone is a pain so I keep those very short and to the point.
Spend the time on a post. Wait until you are at a regular keyboard if necessary. It doesn't have to be perfect. Even a few line spaces here and there to break the text up into a few paragraphs REALLY helps!!
