The club's in a great position to tell Stub Hub to take specific tickets down. Due to Ticketing Regulations in the UK:
http://www.inbrief.co.uk/football-law/ticket-touting-and-football/
and that EFC set the ground's regulations:

Its also a breach of the EFC Season Ticket Terms and Conditions:

5.2 The Club issues to the Purchaser the Ticket(s) for the Purchaser’s sole use. The Purchaser shall not resell, assign or (save as set out in this Clause 5) transfer their Ticket(s) (or the benefit of it or them) to any other person without the prior written consent of the Club. References in these Terms to reselling Tickets includes offering to sell a Ticket, exposing a Ticket for sale, making a Ticket available for sale by another person and/or advertising that a Ticket is available for purchase. For the avoidance of doubt (and by way of example only), a Ticket may not be offered as a prize in any promotion or competition or transferred, lent or sold to any third party as part of a hospitality or travel package, given to a third party who agrees to buy another good or service or used for any other commercial purpose save as expressly authorised by the Premier League and/or the Club.
5.4 If more than one Season Ticket is issued to the Purchaser, or the Purchaser cannot attend a particular Match included within their Season Ticket, the Purchaser may transfer the use of such Season Ticket(s) for that Match to a natural person (each a “Guest”) in one of the following ways: (i) with the express written consent of the Club; (ii) via the Club’s official ticketing exchange system (if any), details of which will be available on the Website; or (iii) to a Guest provided that: (A) the Guest is known to the Purchaser personally; (B) it is for the Guest’s personal use only; (C) the Guest would be entitled (under these Terms) to purchase such Ticket and attend such Match; (D) the sale or transfer takes place in consideration of no payment or benefit which is in excess of the pro rata value of the Season Ticket for that Match (calculated as the total price for the Season Ticket divided by the total number of Matches covered by the Season Ticket); and (E) the sale or transfer does not take place during the course of any business or for the purpose of facilitating any third party’s business
The issue isn't Stub Hub. The issue is that there is no technical means to report abuse of season tickets directly in Stub Hub/to the club. Without emailing or telephoning.
Or that the club isn't proactively limiting the maximum price that can be asked for.
Certainly - ANYONE buying a season ticket just to sell it all (19 games) on Stub Hub should immediately forfeit the ticket.
As that is definitively - ticket touting.
Supply and demand is fuelling this (34000 season tickets and limited stadium capacity). That the club need to get a grip of.
