Nick, if you are reading this, and i am sure you are.
The best course of action here is to stop with all the lies. Just stop.
You can still pick the low hanging fruit by marketing yourself to “intro to dressage” people. Hell, i could do that myself and i have only ever shown training level.
You are not doing yourself any favors by spinning this web. You have been completely outed and need to go back to the den and devise another strategy. All is not lost. If you persist with your lies people are going to get very ugly with you. It has already been started. If you want to market yourself as an up-down trainer, or someone who can help rank newbies get the hang of dressage, then do that. You are not even qualified to do this but it would at least be honest.
If you insist on perpetuating your lies and defending them at all costs I will (among others) create a flyer of the summary of everything you have lied about and post it on every single facebook group and horse board in existence. There will be nothing to sue me for, i am but a potential customer who investigated your so-called credentials.
Go now. Stop this. Admit you are full of shit. Admit it to yourself, this will be the hardest thing for you.
Do not try to dupe any others into thinking you are a big name trainer. It’s just going to end badly for you.
