Hi. My first post here, I'm sorry it has to be a negative one because in general I'm very grateful for all your efforts to keep ApexDC++ in shape.
DHT is a security issue for private hubs, period. We can take for granted that many users just accepted the forced update and then went on to share files they thought still were confidential. DHT enabled by default is IMO quite similar to Microsoft's intentions to do the thinking that users should be doing. No offence, my critics is meant to be constructive, but it has to be said that respect for privacy is plain and simple "savoir être" in Internet.
Cheers,
AL
