Viimastel aegadel on veebibottide, mis indekseerivad liiklust, aktiivsus m\u00e4rgatavalt kasvanud. Lisaks normaalselt t\u00f6\u00f6tavatele bottidele on levinud ka «raevukad» botid, mis eiravad robots.txt indekseerimise reegleid, kasutades k\u00fcmneid tuhandeid erinevaid IP-aadresse, teeseldes legitiimseid kasutajaid ja j\u00e4rgimata m\u00f5istlikku p\u00e4ringute k\u00e4sitlemise poliitikat. Need botid loovad serveritele tohutut parasiitset koormust, rikuvad s\u00fcsteemide normaalset t\u00f6\u00f6protsessi ja r\u00f6\u00f6vivad administraatorite aega. Paljud tajuvad selliste botide aktiivsust pahatahtlike tegudena. <\/p>\n

Meetmena sarnaste botide, samuti botide aeglustamiseks, mis skaneerivad parandamata haavatavusi t\u00fc\u00fcpilistes veebirakendustes, pakkus \u00fcks administraator v\u00e4lja «zip-pommi» meetodi. Meetodi p\u00f5hiolemus on see, et veebibotile antakse vastuseks lehe p\u00e4ringule sisu, mis on t\u00f5husalt kokku pakitud «deflate» meetodiga, mille suurus lahtipakkimisel \u00fcletab mitmeid kordi v\u00f5rgus edastatud andmete suuruse. N\u00e4iteks, kasutades «deflate» meetodit, vajab 10 MB suuruse \/dev\/zero sisu lahtipakkimisel 1 GB kettaruumi. «Brotli» kokkusurumismeetodi kasutamisel on saavutatud tase, kus 81 MB edastamine toob kaasa 100 TB andmete lahtipakkimise. <\/p>\n

Sellise kaitse aktiveerimine on v\u00f5imalik l\u00f5ksude loomise kaudu, mis on juurdep\u00e4\u00e4setavad n\u00e4htamatute linkide kaudu, mis on m\u00e4rgitud lipuga ‘rel=»nofollow»‘, mis on v\u00e4lja j\u00e4etud indekseerimisest robots.txt kaudu ja aktiveeruvad piisavalt k\u00f5rge rekurssioonitaseme juures botide puhul, mis p\u00fc\u00fcavad teeselda tavakasutajaid. Praktikas ei soovitata pakutud meetodit rakendada, kuna veebileht v\u00f5ib Google'i musta nimekirja sattuda ja hakata m\u00e4rkima kahjulikuna Chrome brauseris, kui on sisse l\u00fclitatud «Safe Browsing» re\u017eiim.
