Should I report users who have non-activated or multi-wins from years ago?

Just report, but expect that they probably already served their suspension. As far as I know, repeated violations will eventually result in a perma-ban, but if, say, somebody has 20 non-activated wins before they are reported, it counts as a single infraction. That's why it's always good to report them, to catch those who potentially slipped through the cracks.

Report Them it will cause Permanant Suspension .. some win once in month those that are lucky dont active theire wins . its unfair

they either gift the keys here or activating them on other accouns

Support Staff are not able to track all users at all times, so it is helpful for regular users who suspect foul play to contact Support. If you believe someone has been violating our Guidelines, submitting a ticket with supporting evidence would be a good idea. When you write up a ticket, Support Staff focuses their attention on that person's account. If anything is out of order, Support will take appropriate action. If there is no action to be taken (or it has already been taken), you have at least done your due diligence. Also, unless the ticket is a User Report, you may expect to hear back from Support Staff regarding your concerns.

NOTE: User reports do not permit direct feedback from Support. Whether action was taken or not, you will not receive any feedback from Support in your User Report ticket.

One thing that is not helpful is when a user submits a ticket without any explanation and/or evidence. (Yes, we get a lot of those.) If Support cannot figure out what the ticket is even about, we are going to have difficulty following through on it. Another thing to remember is that very old infractions (older than two years) have a high chance of having been seen and dealt with by Support.
