I think point of using the wagered amount is not to stop the trollbox by the new accounts but more like trying to slow down the chat somehow, I know it is already quite fast but if you can manage to find a better way to stop the trollbox going incredibly fast than you can use that but clear choice is always not allowing the new ones to post without hurting anyone.
New ones will either go away soon not gambling too much or will stay here for a long time and become part of the stake family. In either case it keeps the chat box not being too much crowded. I also suggest maybe accounts that have not been active for a long time to actually get a "soft ban" kinda like not wagered but active online type situation where someone who hasn't been talking for over a month comes in again but needs to wait 24 hours to go back to having chat priviliges. Thats just me of course, stake does what it does best and they know how to control the trollbox.
nope , it is exactly to stop spam by new accounts, some individuals can be really annoying
they would create a ton of new alt accounts and post .. obscenities and their valued opinions on how the site is a scam etc.
this makes lives of moderators very hard, plus it is not very good for business when a ton of spammers posting that the site is this and that
besides it is very easy to reach that threshold for a new user even using the free faucet
sometimes it can be frustrating for a new user to not be able to ask questions in chat straight away, but I think it is a reasonable measure
