New things for clans.And

Maybe it was already mentioned, but i couldn't write it down right way in search tab. But here are some things that would help for clans, as i seen its not top requested things here, so first of all is like facebook has to show who from clan seen the message, just the additional window where shows it. Maybe not so actual for clans who have trusted member but for clans who are still getting together folks it would be useful, as in my clan, people are coming in and just don't donate and when you try to speak with them they don't answer, as if they didn't see anything in chat, so it would help with checking if people are ignoring your messages, so that you could free space for other folks.
And second one is black list at least of the clan, because hoppers are annoying sometimes. If we could add them to some kind of list that would prevent them from entering the clan, that would be great. And there would be fields where you write the reason why that particular person should be added to the black list, sometimes it's not only hoppers but also people who were kicked for not donating troops. About next addition i am not sure, i think it would decrease population of clash of clans community, but just to attach this black list information to the persons profile, as what was the reason to add person to the black list so that other clans would see it in advance. But you can work something around it.
Thanks for reading this long post. Maybe someone will agree with me. And for sure write if it cant work in this particular game. Thank you for attention. :)

It seems like basically its a ban from clan system. I have seen multiple players with the same name which might be unfair

I dont think its a good idea...well there is already a way to keep themaway from the clan for a season...just kick..

And if the player leaves before u kick ,invite him back and kick... XD
Enjoy

Well its still can be not preventing from entering, but just list where people who kicked particular person write down reasons for kicking that person, so that in the future we would know if we should put that person for test or just not let him get any troops from the clan. :)
