The OP deleted their question about 10 minutes after I had answered it. As they have not provided any indication of a good reason for them to have deleted it, please help me to undelete it.
@JoseAvilez All three of those questions appear to have been posted by the same user. This looks very much like targeting. I would suggest that you be careful about this in the future. It may be that the questions are all deserving of closure, but it also appears that you found them by reading through that user's profile. This is not okay.
