I’m conducting a small experiment to test how effective reporting spam accounts on Manifold is. I will report 10 unbanned spam accounts as I come across them. Once I’ve reported all 10, I’ll wait a week from the time of the 10th report, then check how many of those accounts have been banned.

This market resolves based on the number of those 10 accounts that have been banned by that time.

Throughout the course of the market, I may share updates on how many accounts I’ve reported so far and how many have already been banned. I will not share the names of the accounts I've reported.

Update 04/07/2025, 04:32 PM (PT): I have reported 10 spam accounts, of which 1 has been banned. This market will resolve based on the number of these 10 accounts that have been banned by April 14th, a week from this update.

@traders I reported the 10th spam account a few minutes ago. This market will resolve a week from now!

@evan [deleted, I didn't read the description close enough]

@traders Account #1 has been banned!

opened a Ṁ10 NO at 24% order

My experience is that using the report button on markets and accounts does not seem to get attention. However, creating a market about it will. Maybe it balances out

@GleamingRhino what about using the mods tag while making a joke at the spammer's expense in the comments?

@TheAllMemeingEye using the mods tag in market comments has always been an option that works promptly. However this unnecessarily reveals you as the reporter publicly so I am not a huge fan of it and wish I didn’t have to. This also does not work for spammers who have not made markets or comments yet (like the numerous junk 88 accounts that I have yet to see banned).

Wait, how can an account be doing spam if they aren't making markets or comments? Also what is junk 88?

@TheAllMemeingEye if you do a search for “88”, in the users section there are a lot of accounts doing SEO like this. Some have been banned but not all.

@GleamingRhino ah thanks that makes sense, I forgot about bios

What is the criteria you personally use to decide whether an account is spam and should be reported?

@TheAllMemeingEye Usually, it's because they make comments like this:

Another hallmark of a spam account is when the account does not bet and only creates markets with no resolution criteria and that have a bunch of external links in the description, like this one.

@evan thanks, was just trying to make sure you're not sending loads of false positives by e.g. reporting users you disagree with, but it seems you're using regular sane criteria of reporting obvious advertising bots
