    Robots.txt e esclusione user-agent

    Stavo cercando una versione della pagina di un grosso portale italiano con archive.org ma inserendo il nome del dominio mi son trovato la risposta che il crawling non era abilitato a causa delle impostazioni del robots.txt.
    A questo punto curiosando come fosse configurato questo robots.txt ho visto che vengono messi in disallow certi user-agent. Controllando anche su giorgiotave.it esiste una lista, ma è diversa da questa.
    La mia domanda a questo punto è: è una best-practise da adottare quella di bloccare certi user-agent?
    Esiste una lista aggiornata e affidabile degli user-agent che è meglio siano bloccati?
