Can the use of WebHogs (or RandScan) get me in trouble?
Most probably not. The author has used the program extensively with no problem or complaint whatsoever. Basically, the program retrieves web pages as a browser does. Check your own sources including your internet service provider if in doubt. WebHogs requests a web page using the same method as a browser and is not noteworthy in that respect. Whether it is WebHogs or your regular browser, most web servers will log your IP address for its records. Generally, if you use any program at all in a questionable manner, you most probably can be easily identified.
