Legit pools won't have SOL as base_mint, i am happy to filter them on downstream as long as dex solana trades shows valid numbers for pumpswap.

In general this type of trades/pools cause dex_solana trades have pumpswap enourmoues not realistic volume in terms of business(fundamental KPIs) Including flag washing volume or not would require big changes in dex table.

The Trick: sell then buy on an Inverted Pool
This is the key insight. Because Pool 1 has SOL as base_mint and C0IN as quote_mint (inverted), the instruction names are flipped from what you'd expect:

So the bot is exploiting the inverted pool orientation — using sell to go SOL→C0IN and buy to go C0IN→SOL, on the same pool, in the same transaction.
Result:
C0IN spent (net loss)~154,260 C0IN
SOL net 0

The bot spent ~154,260 C0IN (plus ~8,385 C0IN in protocol fees) to get back the exact same 500 SOL. This is not arbitrage profit — it's a net loss in C0IN terms.
