A lovetroll is a troll that gives and takes love in a positive way.
There is absolutely nothing negative to a lovetroll at all.
It is also in no way related to the pejorative 'troll' which is known on forums.

Solarpunk is a movement focused on a positive, ecological vision for a future where technology is used for human-centric and ecocentric purposes. It is a literary, artistic and aesthetic sub-genre and is also closely tied to eco-political activism. Solarpunk narratives have a distinctly positive and utopian foundation in contrast to the often dystopian visions found within other "punk" science fiction genres.
