How do you guys deal with free tier abuse for your SaaS?

As the title suggests I’ve been having an issue recently where I’ve had persons abuse the free tier I have for my SaaS where in one particular instance I had a wave of over 300+ accounts try to deploy the same vpn proxy over a day day period. I thought the free tier was limited enough that persons would maybe pay for a plan but clearly that’s not the case. It’s getting to the point where it’s now costing me more to keep the project running when I haven’t even made a dollar from the project to date.

How do you guys usually handle these type of things? I’m thinking of switching to a trial instead of a permanent free tier but I’m not sure if there’s something else I can try before making that switch. As someone who’s benefited from free tiers of other platforms I would want to extend that to users of my platform but at this rate I need to make a decision.
