bots harvest statistics for web analytis service and cause no harm. I don’t think this can be an issue, since nobody complains on bots that belong to #Google
and other search engines. Semalt crawler bots have 100% bounce rate and don’t click on advertising banners (cpc, cpa, cpm systems) or extend links. All the visits are automatic and random.
