Bots crawl the web and keep on crawling. Google, Yahoo and Bing bots are the ones which index your side within the search engine results.
Search Engine Bots use up a lot of server resources and may even cause your server to crash or ave abnormal high load. If your site does not need indexing then there is no point in letting bots browse through your site and eat up precious server resources.
Google has very powerful bots which can browse upto 1000 pages of your site within a minute (am pretty sure that the actual number is more in terms of pages crawled per minute)
There are certain set of bots which steal content from your site or just visit your site to leave a mark of their visit. These are bad bots. YesUp is one of those such bad asses! If you find any bot browsing your site, follow it up. If its not a online proxy browser then block its ip from your server.
