I believe that #polish community was one of the best organised to find on Steem during the crypto boom in late 2017 and start od the 2018. Rewards were small, but people were publishing and chatting a lot.
We had a dedicated "polish" tag with smaller thematic tags like "pl-blog" or "pl-cryptocurency". Number of curators where discovering good posts everyday to send them further to whales (private and ocdb). @Noisy established Wise to manage big valued votes. Plagiarism and bots were downvoted heavily by users. #polish trending was quite organic. My site Steemweb.pl was published to help new users to discover popular polish tags and find community statistics. And then..
My database was build from all post with polish tags throughout the more than a year. One statistics contains data of users activity, based on the minimal action everyday - upvote (and minimal 1 publication in the past in polish tag). As you can see below:
This chart starts on 16.06.2018 and ends on 30.09.2019
New users are still coming to polish tags and using them actively but growth is much slower (blue line).
Because of that there is dramatic decline in active polish users (red line).
#polish tag usage from the beginning of the Steem blockchain
I was curious how much community is losing because of inactive Steem Power and made this chart:
To be more specific, today this data looks like this:
In the last 24h polish community didn't use $30.35 (SBD) from upvotes (sum)! (for polish publishers 30$ daily is much)
I even have implemented a public "Hall of Fame":

It is quite depressing statistic, but this is what happens to Steem $-driven community after crypto crash.
