It's not that people are aggro about the blocks themselves, it's the blocking, on top of the completely inorganic social dynamic they've created, on top of the rabid adherence to cliqueism they all maintain, with every single one of them deliberately misrepresenting what they're doing while condemning the original social culture fostered on this platform.
Nobody is "sperging" about it beyond criticizing them for the splintering of a site that, while they're content to mess it up, most of them still have their Gab accounts. They're dual citizens in a digital landscape.
