Does anyone else think there's something suspicious going on with games between Grandh and another player?? You'll see who I'm referring to if you just look at the game history.

Indeed this seems like elo-cheating.
Not only is game conceeded as soon as possible, there also seem to be deliberate bad moves (not capturing when they can, offering blots all the time when no need to) - at least in the game i checked.
And also they have played from same IP in the past (you can see that by inviting both to a table).
You can fill a report in such a case

What is the process for bringing this to the attention of the admins? Wouldn't the algo report suspicious activity like this? I mean, it is so obvious you'd have to be blind not to see what is going on.

go to their profile page by clicking their username. Select report this player.

The mods have taken action against this player by limiting access for a little more than one week. What happens after that?

If I recall correctly, if the behavior continues the access limitation expands in duration, up to the account being disabled (and in some cases, the IP being blocked).

For future reference, it is not a good idea to call out suspicious activity by username in the forums, no matter how obvious it may seem. The better course of action would be to describe the suspicious activity, and people will explain how to report it (or how it is not really suspicious).
