There really aren't any norms. Different players have different play styles. The term RoR really came from clan servers, and even the concept of "retalling" came from there as well.
Basically, players on clan servers decided to band together to protect each other. If someone gets attacked, one of the clan members would attack back the attacker to get the land back, in the event the original target couldn't retal himself. This discouraged people from attacking players that are in a clan.
Retal on Retal (basically a retal on a retal) is generally seen as a provocative move on clan servers, sometimes leading to clan wars, so it is frowned on.
Now on solo servers like this one, everyone is their own clan. So the concept of retals is really a leftover from clan servers, but is somewhat enforced by the different GDI rules on solo servers (to the GDI rules on clan servers). If you attack someone, and that someone chooses to retal you 6 weeks later (or 4 days later for Express timescale) for 10x the land, would you accept that? If you don't, you can Retal that Retal - that is, you do not accept the Retal, and choose to treat it as a new attack, and you are retalling that accordingly. But since you have now made a total of 2 attacks on him if you RoR, you open yourself up to special attacks (war) because that's how GDI works.
So there's really no positive or negative thing about RoR, the term itself doesn't carry any positive or negative meaning, it is just a term to describe what it exactly is - a RoR from one country's point of view, and a normal Retal on a very late attack from the other point of view.
Generally speaking, it is accepted that retal windows on solo servers are reset-long. But, some players don't accept that, and try to enforce say a 72-hour window or maybe a week (on Primary), and any longer than that, they would treat it as a new attack, and "RoR" it, and such players either get away with it, or they end up in war.
