It definitely should help over time. It's 1 change in a long list of many that will fix the issue of irrelevant content on Steemleo (and other tribes as well).
Another thing recently implemented (but not yet announced) is the filtering of tags that we have added. You may notice a cleaner feed on Steemleo as we've filtered out the following tags:
- Appics
- Actifit
- Share2steem
- Steemhunt
- Dlike
We are also regularly policing tags and have a set of guidelines in the works as well. Tag abuse is one of our top priorities at the moment.
