Безопасен ли snapengage.com?

From what I can tell, you mostly see snapengage scripts on sites that have bought use of their instant chat plug in (for customer service). In general, you won't need to enable this script, unless you want to use the chat feature, but I don't see any obvious harm either. The site itself, of course, is the front page for a reputable site, and for that reason is very likely safe. But chances are, this isn't your use case....
