Link generation code:
- `n`, `b` and `z` are dynamic (random) on each reload
- `%2` and `%3` for n and b don't change
- The main number for `n` and `b` is always equal
- `z` is always the `n`/`b` main number + 3
- Link middle part calculation stays the same
- `href = $1 + ($2 % $3 + $4 % $5) + $6`
- `$1` is always `/d/XXX` where XXX is dependent on the file
- `$2`, `$3`, `$4` and `$5` are dynamic and randomly generated on each reload
- `$2` is always the same as `$4`
- `$6` is dependent on the file
- The numbers in the calculation part ($2`, `$3`, `$4` and `$5`) are hard coded
```
