To whom this may apply:
I'm seeing a lot of people who have uniques log on for a minute here and there, sometimes multiple times a day. I'm assuming they are doing this to appear active.
However, you may end up harming your interests by doing this, as it's easier to overlook a period of prolonged play in such a massive list of brief log ons, meaning it will appear you weren't active enough and you may end up in Unique Jail. Those minutes here and there do not count towards your activity, so all in all, it's pointless and may actually achieve the opposite of what you intended.
