When a user is getting banned from suggesting edits he/she will have just a generic message telling they can't suggest edits anymore. It's really not trivial why this happened.
Same way that a question ban message contains a link to the relevant FAQ here on Meta Stack Overflow, it will be just proper to add a link to the How do suggested edits work? FAQ when a user get the suggested edits ban and try to suggest an edit.
This will render such questions "obsolete", and I think I have seen a steady increase in their volume lately.
