Great advice and information. There are some great curation guilds out there. Many of them will also have Discord channels so you can chat and get to know the people behind the programs. I stick with these ones so I know what they're about before joining. Unfortunately there are those scammers who just want your SBD to join up, and will then disappear. It's difficult to tell the good from the bad sometimes.
Yes, there are some good ones. The problem is that people like my brother don't have the time to do all of the research it takes to work out which is which. This means that he ends up avoiding all which is not great for him or his content.
