Yes that is true,
@*****alS , this happens now and then.
First - I give them a 2nd chance, and by a prepared private mail I ask them to attentively read my profile text and write a "proper" second one, showing me they have carefully checked my text and came to the result that there were some matching points of interest. And I announce that I will only reply if this is done.
But - you art right, DreimalS, usually it is not worthwhile giving them the 2nd chance. There are a few exceptions to the rule.
Either I then start ignoring their following messages.
Only in case they really don't stop bothering me, I use the button to "officially" end the conversation.
