Hello,
I agree with what Giuseppe Lavagetto and Jaime Crespo said.
In my case, I am now getting review requests from several repos I contributed some time in the past, but for which I'm not a qualified reviewer. The plugin is also adding bots to review changes such as in https://gerrit.wikimedia.org/r/485174.
While I think it is certainly a good idea to help people find reviewers for their patches, I feel this plugin as it is now is going to achieve the contrary (mail blindness due to too many emails).
I suggest we disable the plugin until at least Paladox's blacklist could be implemented and so we are given the choice to opt-out from it.
Thank you, M.
