I have been using zipbombs and they were effective to some extent. Then I had the smart idea to write about it on HN [0]. The result was a flood of new types of bots that overwhelmed my $6 server. For ~100k daily request, it wasn't sustainable to serve 1 to 10MB payloads.
I've updated my heuristic to only serve the worst offenders, and created honeypots to collect ips and repond with 403s. After a few months, and some other spam tricks I'll keep to myself this time, my traffic is back to something reasonable again.
