I use Reddit from time to time but it is flooded with so many random topics and other stuff that it feels difficult for a site to really stand out and drive audience to the site. I think there ways for Betfury to market themself then be active on Reddit.
Just as Reddit seems messy and confusing to you, Reddit seems messy and confusing to me. I made a Reddit account a long time ago, but my Reddit account now appears suspended to me. In other words, Reddit seems to be the only social media that seems confusing to me. However, Betfury may use Reddit as a social media platform, but in that case, most general users, where Reddit accounts are not authorized, will not see Betfury's marketing on Reddit.
