We've had this a couple times at least in @spinvest accounts, with steem-engine tokens. The user interface does not say this, but it should. I believe Steem DELI will not allow the @ symbol and kicks it back. But S-E token DELI allows it and you have to wait 5 days to reclaim deli sent to a fake account!
PLEASE DO NOT USE THE "@" SYMBOL WHEN SENDING DELI TO SPINVEST-NEO!!!
Thanks for viewing!
