Folks have made the point that people who use the block repeatedly in one evening, and then return the next evening, are abusing that protocol, which is meant to be used when someone wants to say "I would have to seriously consider leaving this movement if this particular proposal was consensed upon."
If the group overrides the block, and the person who blocked just continues on in the movement as if nothing happened, then the question arises: "Why didn't this person seriously consider leaving the movement, as they suggested they would when they used the block?"
This appears to be a case of people repurposing a protocol for their own purposes. The block protocol does not mean the same thing to them as it does to the rest of the community. Some argue that this repurposing is in violation of the "Principles of Solidarity," but I'm not sure exactly how. The Principles of Solidarity state
Through a direct democratic process, we have come together as individuals and crafted these principles of solidarity, which are points of unity that include but are not limited to:
Engaging in direct and transparent participatory democracy;
Exercising personal and collective responsibility;
Recognizing individuals’ inherent privilege and the influence it has on all interactions;
Empowering one another against all forms of oppression;
Redefining how labor is valued;
The sanctity of individual privacy;
The belief that education is human right; and
Endeavoring to practice and support wide application of open source.
We are daring to imagine a new socio-political and economic alternative that offers greater possibility of equality.
