DDL2017 delegates are being targeted by scammers, organizers warn. Callers claiming to be from the DDL organization have been phoning delegates and offering to book accommodations for the conference and then ask for credit card information. Anyone who has provided credit or debit card details to one of these callers should contact their bank immediately.
