Pre.....cisely Proton !
In a town of just 17,000 people, four of them landing at the same time is pretty unlikely.
Seen similar things happen in tiny towns in Wiltshire - from memory three once appeared within days in Malmesbury ! Riiiight.
Suspect it's Sergei and his fellow team of teenage fake profile makers, scooping up or re-using some old profiles. And being lazy by not doing his homework on English/Welsh town sizes before collecting his private gallery fees for fake photos from gullible punters.
Good luck getting a meet gents.
Coincidental that they're all priced at £3.00 for 24 hours viewing?
I think not............but by all means call me cynical if anyone's lucky enough to TOFTT and I'm proven wrong.
