Unfortunately, anything that’s publicly posted online can be stolen by someone with enough drive to do so.

If it’s a bot doing it, both https://www.ads-software.com/plugins/blackhole-bad-bots/ and https://www.ads-software.com/plugins/block-bad-queries/ may help.

Was the plugin active before your content was stolen?

The plugin might prevent content theft, but once it’s happened, your only recourse is to file a DMCA report with the site’s hosting provider.
