Spam filtering is coming to Warpcast. 

Over the last 3 months, we've labelled thousands of spammy accounts by hand and @akshaan has carefully trained an ML model to do this automatically. 

We're rolling out this model starting today, and it will significantly improve the user experience.

Spam is posting irrelevant content in public spaces to farm reactions and follows. 

Some examples: 
- Posting irrelevant replies to someone's cast 
- Posting irrelevant content in a channel
- Mentioning or recasting users unnecessarily

Here's a one from a few minutes ago:

Warpcast won't show casts from spammers in public spaces. 

They won't show up in the channels, replies and notifications of people who don't follow them. 

Warpcast does promise that content will always be visible to followers (sufficient decentralization), even if a user is labelled spammy.

Our spam model is going to start labelling new accounts today, and over time will roll out to 100% of accounts. 

The labels aren’t visible at this time, though we plan to make them publicly available to other applications just like the power badge.

the model mostly looks at message content and location to determine spam. 

if you make a cast that annoys one person, that's not really spam. 

if you make the same cast asking people to follow you in 5 high traffic channels, you'll get the spam label.

Is there a plan for how to handle false positives? I'm always worried about being labeled as a spam account because of one stupid comment someone didn't like.

How will false positives be handled? Is there manual review in the loop at all (eg for appeals?)

Can a spam-labelled account ever be labeled good in the future?

In the next three weeks, cast actions & warpcast nerfing in reply tips (im guessing they will) will kill the meta memecoin attention distribution

and so it begins

My Japanese CTO & Creative Director who create frames, run channels, post good content were shadowbanned today. My English speaking team member & I weren't.

My Japanese team members now don't want to use Japanese on FC.

I know there're growing pains w/ user growth, but something needs to change.

This is one of the reasons I'm highly skeptical about spam filtering. There are going to be a lot of edge cases that the model won't handle properly, resulting in people getting unfairly shadowbanned. Most of those people will never trust warpcast again.

will do my best to not become a false positive food for the model

amazing! is "report cast" an input to the model, or thats just used for manual hiding? i've been using that more hoping it helps

Cool that you try to go against spam and improve discoverability. I hope this is not escalating into censorship. I would prefer filters that users can configure themselves such as not seeing posts from new accounts, accounts with low engagement rates etc.

Also, since I'm quite sure that badged accounts don't get notifications for my actions (replies mostly) does it mean I'm already in a certain way flagged as spammy? Asking to understand if that's the normal behaviour.

Great to read! Everyday this gets better than X

Can you explain how the power badge works?

I see many big accounts using the exact "spammy" type of actions, without punishment. Yet smaller accounts seem to get pushed.

How and when do people receive the badge? I had it, then I somehow lost it??
