I've used UptimeRobot's Free Plan for YEARS to monitor two completely private, non-commercial websites with very low activity. And now, out of the blue, I get an email accusing me of violating their Terms of Service by supposedly using the Free Plan for "commercial purposes."This is an absolute insult. Without any proof, I'm forced to either jump through hoops by filling out some survey to prove my innocence or pay for a commercial plan. Why am I, a loyal and personal user, being treated like this?It's appalling that a service I once trusted now resorts to such aggressive tactics to squeeze money out of users. If UptimeRobot doesn’t want to offer a free plan anymore, they should just say so, not accuse long-term users of violating their rules without cause.I’ll be moving to another service immediately. If you're thinking about using UptimeRobot, be warned: they clearly have no respect for their users. Terrible experience!
