First of all it is necessary to agree on what the subject of the discussion is.
So far the thread includes opinions on likes, but not stating if it's on main site or in the community, and about reputation which is a main site feature.
Though log-in gives access to both the community and the main site, they work independent of each other.
Likes in the community doesn't affect your status or power on the main site.
A negative reputation only has effect on what a user is able to do on main site, but It doesn't affect the TL status in the community.
Likes on main site has influence on your power rating.
In FAQ it says: "You can Rate only If your “POWER” is NOT 0."
As [Login to see the link] according to the profile has a power of 6.02, there is no restrictions on main site.
About the negative reputation it says: "And we will check all members with LOW "Rating", who may get banned for their bad deeds."
Nobody gets banned only because of a negative reputation. It's a decision made by the admin and mods based on the users general behavior.
The rules about power and rating are for main site not the community
