It's a good idea but probably not wise to have a generic all-purpose reply that is simply copy-and-pasted into comment sections, but rather a "skeleton" of a reply that can be fleshed out with a commenter's own words to address a specific article and avoid the appearance of a "canned" reply.
I've thought of that. Sure would hate to have 100 identical comments coming back to haunt the Bitcoin community. But a draft as you described is surely not out of the question. That's one reason why I opt to have this thread, to garner suggestions such as yours. Thank you, edd.
What if a simpler comment would suffice? One such as, "Perhaps the answer lies here." Where 'here' is a hyperlink (or a hyperlink follows) to a well written blog post outlining a 3% Solution, or any other plan, to help charities in the economical times we currently live in, with Bitcoin, of course, as the main theme/solution. All we would need is the Blog post written (perhaps a similar one already exists), then a select few of us take it on our own accord and pen such a sentence in our own wording, each time changing the wording slightly to be in sync with the articles. Each article would have to be read prior to any posting of comments, oppose to simply spamming comments sections for the sake of it being a numbers game. It'll be an ongoing process. Not one starting today and ending next week. We'll even have to read some of the most recent comments to make double sure we're not posting on top one another, thus not double linking.
