Every dame right, As far the merit isn't up to 50 per sender there is defaulter here both from the receiver and the senders. I think OP and other users are clarified on issues like this. It still not out of place to raise a concern as this so that the community can trash it once and for all.
you're not entirely wrong I must say
I would also like to eliminate these things, these ugliness
but it's not easy unfortunately, for this system of merits and system of trust are two separate things
It is very important to be vigilant but it is not easy to hit these people
I put them in ignore and that's it, could that be a solution?
