You know, you hit the spot here: Some even make the mistake of speaking against gambling while they are carrying a gambling signature.
You can't pretend you like gambling just because you're wearing a gambling signature. Unless it is stated in the campaign thread, I guess we're allowed to speak freely about it.
It`s a subject for another thread, but I don`t know if people will be totally honest to answer if they believe in the service they are promoting

More than 50% of the things people promote are likely not something they personally like or use. If ChipMixer had accepted you in their sig campaign, I'm more than sure you'd accept it even if you do not use/support their service. The amount of BTC you're going to earn will trigger a positive answer to their offer. It's a psychological thing we do as humans.
