Since the first eroFame in 2010, exhibitors have reported receiving mails from companies claiming that a visitor list for the eroFame in Hannover is for sale. Currently, a visitor list for eroFame 2021 is being offered. The eroFame strongly advises against purchasing such a list. The e-mails are sent from mail addresses with domains such as leadtechstudio.com, octantech.com, businessleades.com, tradesways.com or oct10expoleads.com. To arouse respectability, the senders often adorn themselves with titles such as ‘Event Coordinator’ or ‘Trade Show Commissioner’. There is no visitor list which can be purchased or otherwise obtained.
