I think the forum content (except for a few sections) is visible to everyone even without an account. So if there is some agreement on it then the forum can be locked and stop google or as a matter of fact any other search engine from crawling the contents here. I myself have seen many a times that the links are shared on telegram moment they are shared here which I would be ok with.
The important bit is to save the contents of the group buy for being leaked. There are a few members who participate in the group buy and then leak it every where. I believe tightening of the group buy policies would definitely help the leaks from happening which would come at a cost. By tightening I mean only credible members should be considered to be group buy participants. This will eventually bring the number of participants down and the cost of the group buy would inch up but with the chain of trust of a respectable member being a part of the group buy the chances of the leak can be minimized. I know gadfly has always mentioned that some of the members with less number of posts have been left out of the group buy.
A special note of appreciation to gadfly who has given more than expected to this forum and eventually land up being abused because of some crooks around.
Thanks once again gadfly.^:)^ ^:)^
