Recently, a bunch of testnet incentives and point task spam has flooded the scene, and everyone is guessing whether the mainnet will issue tokens... Frankly, this kind of "noise" is overwhelming, and it's easiest to accidentally click on a phishing site. The mnemonic phrase is a red line: if any webpage/customer service/robot asks you to fill it in, block them immediately—don't tell me "I'll just try." Also, with signature authorization, don't just click "OK" on pop-ups, especially those with unlimited permissions or ones you don't understand; better to miss out on airdrops than hand over your wallet as charity. The only noise reduction strategy is: only access from the project's official domain, bookmark the fixed entry point, and don't follow links in groups—start with this.
