That simple question. If you check in the Privacy options, you can see your contacts list (allow list) as well as your list of blocked people, there's a button to view people that has added you also.
Someone deleted me from his/her contact list but I can still see his/her online status and can send him/her messages, so she/he didn't blocked me. That means I don't see him/her anymore in the list of people who added me. Of course, what this contact wants is that he/she is not supposed to talk to me anymore but wants to see that I still am willing to talk to him/her.
What I want to do is that he/she couldn't see that I still have him/her added in my list, to just tell him/her that "I don't have him/her in my contact list anymore". But actually I don't want to do that, I still want to see his/her online status, and still have the ability to send him/her messages (for some purposes at future).
I don't want to specify my reasons, what happened etc xD So I also don't expect advices like: make a new account and add him/her, but don't tell him who you are and be friends so that you could see his/her online status in that new account and so that you can actually delete that contact from your former account.
BTW. Is it possible to send a message to someone that obviously hasn't blocked you but that you don't have in your contact list? That's the reason of the problem. But I also want to see his/her nick and online status. To keep a watch on someone but not telling him/her I'm doing that (because he/she can't see that I still have him/her in my contact list if he/she take a look at "people that has added you" list).
Any plugin? advice?
