PookaMustard: With freebies come your insects, and whether you put bug deterrent on your plants or not, they'll still be desperate to get to your plants and may perhaps hang around till you leave the plants defenseless. That's how it works. So stop all giveaways and we'll talk.
Just because the insects still keep coming doesn't mean it's wrong to do something to try to keep them out.
In any case, they're not asking for an end to all giveaways: They're asking for people to simply stop posting codes openly (as well as trade openly with strangers) because they attract scammers and they encourage scamming behaviour. And over the years, the community
has tried to come up with systems to allow people to freely do giveaways or trades while minimizing risk; things like MAHAYO, encouraging people to participate in creative activities to enter, or even an escrow service that several users tried to start up. All of those solutions were ignored.
In essence the argument seems to be that people should be allowed to continue to particpate in behaviour that is demonstrably known to be harmful to the community, in the name of personal freedom.
