I believe the guy you are talking about was called “The RQMS”. Probably nicknamed “Captain Shouty” because he wrote his ads in capital letters.
Some of his descriptions were wildly inaccurate and in short, total bullshit.
I do actually miss the guy, I loved reading his ads because they genuinely made me laugh out loud. The “airsmith” was a personal highlight.
I wonder where he’s pedalling all his crap now Freeads banned airguns....
