All, at least, partially true. However a painting is fixed and doesn't change, unlike our tanks. Pictures of beautiful tanks may represent a tank that falls apart in the next month. While I believe that all of your pictures are, truly, your tanks and represent the current state of your tanks and your ability to maintain that state, I have no proof of it ...nor could it be proven readily.
No one sees risk until it is too late, just ask Equifax. I have reason to fear the "Dark Web."
The change is actually what makes it more interesting. I really look forward to seeing what's new in the dozens and dozens of journals that I follow. Not to hear what's new, but to see what's new. It's what makes the forum fun and brings people back (and new people to the hobby!).
Without pics this site would die. Who is going to follow a journal where someone "tells" you how wonderful things are going? Or "tells" you how they changed their layout and how fantastic it is. Or "tells" you they changed this or that and their plants are peaking and oh what a beautiful flowery stem. Frankly without pics it's not very compelling, inspiring, instructive, or worth reading, at least to me.
As to proof, I don't know what more one could possibly do than post regular pictures of their results. Could it all be a mirage? Well there is that one in a million chance, but I don't think that is much of a worry or risk for a bunch of folks who gather here to enhance their enjoyment of the hobby. Most folks are here for the right reasons, sharing their journey while trying to learn and improve, and being involved in a community that shares their interest.
When I got started in this hobby, I spent a great deal of time reading journals here. My "go to" was the OG Burr740 75G journey. And it wasn't because of what he said, it's because of what he showed. While there were lots of folks spouting off about this and that, he was showing me the goods. Seeing is believing, and I learned quickly to tune the pretenders out. It was a wise decision.
And if someone from the "dark web' is spending their time here, well they must be bored out of their minds and not very good at it. In the scheme of things, this is a very small community with no commerce. Does not seem like a very attractive target, at least to me.
