It's now like a game. 1xBit will come around, offer the shit posters a good amount of money, they will wear their signature and start trolling around. In the current Feedback system I don't think giving red tag is a good practice, but surely we all can leave neutral and alert good projects not to hire them.
If anyone else deletes the signature in a short period of time I will change the feedback from negative to neutral. I don't think it is necessary to be angry with someone who makes a mistake, realizes it and corrects the action quickly.
I will be leaving neutral to all these accounts above.
