Welcome to Waze, Arthur. You seem like a very enthusiastic editor, and you probably have a lot to contribute. Just want to point out a couple of things...
Many drivers will pave roads from the client app, and never come back to edit them. So they stay on the editor as a red road that never makes it back to the client for everyone to use.
It's the area manager's job to decide whether they're real roads or if someone was just paving roads while riding around a field on a lawn mower. Being that llayden is a Level 3 Area Manager, he was not really doing anything unethical. You gained far more points by paving than you would by editing the roads, although I understand your frustration, in that you would have gotten even more by editing.
If you let llayden know that you actually intend to edit the roads you've paved (once again...this is not something we see every day), I'm sure he'll resist the urge to clean up the red roads. Area managers are usually more than willing to work in cooperation with other editors.
ETA: llayden has been active in the forums within the past couple of days. I assume that you sent him a PM and that's what you've copied as your second post. I did a quick search of Longford, Ireland in the editor on the world server and the first 6 segments I clicked on, you had edited 3 and llayden had edited 3. I don't know how much area llayden covers, but you might be neighbors.
One thing you really need to watch for is things like this: (see highlighted segment)https://world.waze.com/cartouche/?zoom= ... =104626074
Since the aerial is at such a low resolution, I can't really see what's there, but I assume these two roads intersect each other. There's no junction connecting the two roads.
