I may just be slow ... but this could be an ingenious idea!
In the past 24 hours I have been blocked by three individuals. I have interacted with none of the theee. All three have visited my profile.
It suddenly occurs to me that this is a great time saver method. It will enable me not to visit the same profile of people that don't interest me again in a week or two. Or in a month or more. What an ingenious method to assist my memory. I have an entirely new outlook on blocking and being blocked.
