I think it's pretty obvious. The rather sad spamming of the topic and talking to yourself when nobody else is replying. The need to leave your own thread, that you so wanted to have, because you're not getting the attention you crave because you're lonely.
Also, the running horses to 'use up your opponents bandwidth' is complete nonsense. The gif is cached on a user's browser once it's been loaded for the first time. So it's literally doing nothing except take up real estate on the screen.
A lot of people make fun of T for his rapping and street dancing, but I applaud him for trying. It's not easy putting yourself out there. As you say, he's good at his video production business and it's a good job he's doing that as Linda currently has no vocation to fall back once they leave the project.
There is definetely some mental health struggles evident in the appartment. Constantly sleeping, no drive to thrive etc. are classic symptoms of depression (having had family members go through the same). Whilst the best thing would be for both of them to leave the project and start afresh somewhere else, councilling would help them both massively as a first step, in my opinion.
Just to be serious for a moment, but it's night and day different how the appartment has evolved. I've still got the videos from the early days of L&T, where they dressed up the place for Christmas, then themselves as Mr and Mrs Claus and had incredible sex on their Christmas themed sofa, whilst playing rather hardcore porn on the TV. Now I reckon we'll be lucky to get them even putting up a tree
