Don't waste your time expecting help here. they DO NOT tell you WHY an account is rendered inactive/suspended/not seen by others
Accounts are suspended arbitrarily and without cause. A user should be notified about the exact reasons for suspension/ and reasons for rendering an account inactive by Yahoo. Yahoo is not held accountable for any of this and their employees know it. Any employee can make unsupervised decisions as to whether they dislike your opinion or take on anything. That's why they DO NOT provide PROOF of why you can't post or no one sees your posts, etc. Nothing worse than moderators that can hide and don't have to show their faces or tell us who they are and why they do what they do.
