The Newcastle United Supporters' Trust (NUST) have welcomed the club taking "visible action to deter and penalise those who may be profiteering from other fans".
It follows Newcastle cancelling tickets purchased by a school nearly 200 miles away for the Champions League home game against Barcelona.
Forty-five tickets for the match at St James' Park on 18 September were bought by the High School of Dundee - days after 110,000 fans had been in an online queue for the remaining seats.
A spokesman for the school confirmed that they were "informed by the approved provider that the tickets have been cancelled" after purchasing them in good faith.
But it is understood that the tickets came from unauthorised reselling by fans who have now had their season tickets cancelled.

Newcastle do not have an authorised reseller and the only way to sell season tickets is through the club's official platform at face value.
The NUST "welcomed" the club "taking visible action to deter and penalise those who may be profiteering from other fans or, in this baffling case, a number of school pupils from Dundee".
NUST added: "Along with the rise in ticket prices, according to our annual survey, one of the biggest concerns for Newcastle fans is reduced ticket availability due not only to high demand but the selling of tickets through third party sites or other unauthorised means.
"The situation this week has highlighted those frustrations once again. Ticketing can be a divisive subject but we feel united in the stance that tickets belong in the hands of genuine Newcastle United supporters and thank the club for their approach to those who misuse the system. We will continue to request transparency across all ticketing procedures."
