You gave the explanation yourself. You can see it in a lot of coins that it is a bot which does it. Galilel will not engage in such practices or pay third parties to do it. First it is illegal. Second we believe not everybody is stupid. I think this dissuades people who are genuinely interested in the project longterm when they see that the team engages in such tactics or doesn't condemn them just for short term success. Faking volume just to convey people a sense of safety is pure deception and imho reflects very poorly on the project itself. And when you arrive at this point it's not about CMC anymore but rather if this is a project that can be trusted. Besides that like I said it is illegal to do it.
