Limit the widget from showing up after some # has been reached or add a value to disable the traffic from bots…
Hi there, @user5837 
Apologies for the delayed response!
Do I get it right that you’ve face a bot attack on your website, which resulted in the views spike for your Google Reviews widget?
If so, could you please share a link to the page, where this widget is installed? We’ll be happy to take a closer look
