I actually wrote a script that should be useable to create a list of jr members that were demoted to newbies, then received exactly 1 merit so they became jr members again... I already posted it in Theymos's thread: https://bitcointalk.org/index.php?topic=5030366.msg45826022#msg45826022
I'll have to wait untill LoyceV updates his full merit history-db again before i can run it tough... It needs recent merit data.

This being said, this script will just generate a list of potential suspects, I'm pretty sure a lot of people will have received exactly 1 merit in a "legal" way, by asking people with smerit to review their posts...

Eventough this doesn't seem to be the popular opinion, my personal opinion is that we have to strike the iron while it's hot and make a strong stance against anybody who is trying to cheat the new system by buying merits, exchanging merits, begging for merits, blackmailing for merits, buying copper memberships for the sole purpose of spamming,...
If we stick together and systematically tag and ignore anybody caught abusing the system, it will send a strong message to anybody who's just planning on abusing the system... Hopefully leaving us with a cleaner forum.

If other tools are needed, shoot me a PM and i'll see if i can quickly write something to get the job done... I can fetch and parse about any page, even behind cloudflare, or pages only accessible to logged in users. I can combine this data with about any data that's publicly available, either trough an api, a database dump, a flat text database,... If you can show me the data sources and tell me exactly which data to combine with which other data, i can probably create a script to automate the process (no guarantees tough)
