Personally I hate such discussions when derail, since there is never nothing to gain.
Both for users involved and for community here. We are hobbist, passionate both with collectibles and bitcoin, so we are here (probably) only to have fun and spend quiet time together. Trust feedback and trust list it's a personal choice.

My 2 satoshi: I would never force anyone to left a trust (+) on my profile or to add me in a trust list.
If some one will ask something like this I am always a bit suspicious since we have seen in the past people building trust and then become scammers (No! it's not referred to anyone involved in this discussion/topic)...
