Verify that Travian doesn't reuse urls in less than 8 days

[SirWerto]

In The Red Natar, we are using urls as server identifier because Travian doesn't provide them.

Recently, we have discovered that Travian is reusing this urls for new servers, after thinking about it, it's obvious. So we have been mixing servers under the same url.

For fixing that, we have develop the archive system #17 and we have hardcoded a value of 7 days to consider a server finished.

The purpose of this task is to evaluate if this value is enough or we need to lower it. A confirmation by a Travian member via Discord should be enough.
