Spam/Bot Filtering

Purpose: reject noisy accounts and tweets that do not contain useful original prediction signal.

Hard-reject tweets that are mostly:

• referral spam
• generic "edge" posts without reasoning
• copied news without an original view
• automated market summaries
• engagement bait
• no clear event outcome
• pure volume/price alerts without a thesis
• trader-flex threads whose main claim is another trader's PnL or win rate
• "guaranteed" or "free money" market-promo posts
• posts funneling users to referral links, wallet links, profile links, or bio links
• automated daily betting summaries with volume, top-holder, edge, or ROI fields

Typical spam patterns:

I found a Polymarket trader who made 3,100 trades with a 99% win rate...
His positions: https://predictparity.com/...?...code=...

Reject reason: trader_flex_thread or predictparity_referral_link.

Top 2 Polymarket trader can hit $10,000,000 profit next month
Wallet link http://polymarket.com/@rn1?r=deposited

Reject reason: polymarket_referral_link or trader_flex_thread.

go to polymarket - open the market ... buy NO.
that's a guaranteed winning position ... free money

Reject reason: low_value_market_promo.

Who wins this Cs2 BO3...
volume surged 50% in 24h
Edge: 29.0% ROI
Trade in bio

Reject reason: automated_market_summary or referral_or_engagement_spam.

Implementation rules:

retweet -> reject
very short tweet -> reject
referral / code / trade-in-bio pattern -> reject
2+ trader-flex patterns -> reject
2+ automated-market-summary patterns -> reject
2+ low-value-market-promo patterns -> reject
Polymarket profile URL with ?r= referral -> reject
PredictParity URL with ?code= referral -> reject
3+ links with no prediction language -> reject

Signals of usefulness:

• first-person or analyst view
• explicit probability, odds, or directional claim
• market-resolvable event
• deadline or natural resolution window
• nontrivial reasoning
• original thesis, not just "copy this trade"
• reasoning that can be separated from promotional links

Output:

{
  "is_spam": true,
  "reason": "automated_market_summary"
}
