About the bdvoter curation: Sometimes they upvote my content, sometimes not. I have no idea what their reasoning exactly is. I tried to use a #bdcommunity or #bdc tag in the past, didn't change anything.
I try to indeed participate in the social media challenge of Splinterlands twice a week and sometimes bdcvoter stops by and often not. I guess it's just luck.
Yes, I check out threads of inleo as well. Not that much, but I do check it out! :D I think it's a great format, just less suited for me :)
