I am active on INLEO almost everyday and I end up getting an upvote on most of the days. All you need to do is consistently engage. There are times where articles I spend a lot of time writing don't get voted. This is why consistency is important. If you are active at least few days a week with quality content (even on Threads) you will get upvotes.
@leo.voter is the most consistent curation project I have seen when it comes to voting newcomers and high quality authors. It is a lot harder to get upvoted by other projects. Trust me, I have been on HIVE for 8+ years without taking any breaks or hiatus.
