Trovitbot is Trovit's web crawler (also known as a spider). Crawling is a process that Trovit uses to discover new and updated pages and add them to its index.
On average, TrovitBot doesn't access most sites more than once per second. However, due to network lag, this frequency can appear to be slightly faster for brief periods of time.
To block its access, just include the following text in robots.txt:
User-agent: trovitBot
Disallow: /
