Ebay seller "keep_the_faith" now has another 2 "seated" tickets up for sale. Would Rob, or someone else close to The Management, enquire with the ICA how many tickets it's made available to individuals, agencies, third parties and resellers? Given that this gig was always going to be sold out, the tickets should've been limited to two per person. Another thing that could be done (large venues don't bother, but it should be possible for a small venue like the ICA) is to check on the door that tickets haven't been transferred from the purchaser.
Another important point here is that many fans would like to see the Metamatic and/or Cathedral Oceans show, so I hope that John can be persuaded to add an extra London show. If he confirms this now, the bidding frenzy on the ICA tickets will ease off considerably.
