Reset the exp will affect almost all players.The more affected players will be those who don't have any other way than trade exp for events,fossils or legends specially now that the rate to get some pokes and fossils has increased.
I have these idea some time ago,why not hold auctions for exp (I think events should they own auction section too) where these exp pokes (rare events and donations too)could be check for authenticity so no more players will be cheated.Now since check this exp trades will probably take some time these exp auctions could be held in specific times that should be decided for PV staff,it might be a little bothersome to wait some time for trade but players will confident that what they get is legit.
English is not my language I learn watching tv XD
I just read the uptade.Then it would it be better just reduce the points that players get through trading exp
