You know, I don't think there is some sort of dark conspiracy surrounding renfaire tickling. I think it is much simpler. The number of videos decreased simply because the whole activity seemed to die out during the pandemic.
As for Stimulating Feet, I don't think it's the case. The main reason they organised it in a first place was to sell this footage as fetish videos. So I don't think they would purposefully try to show women as not ticklish or resisting tickling to prove anything. On the contrary, they would probably make much more money selling videos with really ticklish women. Also the volunteers were not paid models, but real visitors, so they couldn't "train" them to react in any specific way. Also the participants most likely didn't have a full knowledge what they were getting themselves into. Therefore I would say that people doing the ticking were just really bad at it. Or maybe they were trying not to push it too hard, since they wanted to make "full videos", and the participant could stop this challenge at any second. Or they were simply afraid that if they tickle too hard in a public place, it could cause them problems.
Well, concerning the stop of most renfaire tickling projects (Canelli, Casei Medievale, etc), the primary cause might be simply concerned with the pandemic.
While, with regard to the project of Stimulating Feet (Reflexology Researching), I personally think that its condition may be more complex.
For I've perceived the potential shift of its projectors' intention throughout years.
Specifically, the SF projectors might primarily intended to show the research-aimed productions of tickling their participants (when they just began launching the renfaire project & prior to that).
In the early time of their launch of the renfaire project, they'd made some adjustments about their tickling ways & tools on different participants, which showed some variety of their tickling ways & tools and of different participants reactions.
Such adjustments seemed to peak in 2024 when the name of their channel changed from 'Stimulating Feet' to 'Reflexology Researching'.
In the earliest footages of the current channel 'Reflexology Researching', the participants of the renfaire project tended to show some obvious ticklish reactions.
Even in one early footage, the RR ler tried to tickle a participant with her fingernails (and this participant only had obvious ticklish reaction when she's tickled by fingernails but not by the other tools):

However, since 2025, the newly shown footages have been presented consistently similar tickling ways with virtually the same tools.
Accordingly, the new participants have shown generally & significantly less ticklish reactions (especially in the footages that're published in the very late 2025 & 2026).
For me, such a significant shift of presenting scenes indicates a potential shift of the intention of the SF/RR projectors.
That is, those projectors have seemed to have their increasing intention of presenting the seeming non-ticklishness of the female participants.
On the other hand, they can still sell much money with such videos, because many men still enjoy just watching the females lees being tickled with no obvious ticklish reactions.
In a word, from 'Stimulating Feet' to 'Reflexology Researching', the projectors (of the renfaire project at least) have been likely to make their productions with an increasing intention of showing the fetish-related theme & the female participants' (seeming) toughness of resisting being tickled.
Anyway, these above are based on my personal speculation. I (and probably nobody) can offer any solid evidence for them.
So, I welcome to receive the disagreement on my speculation.
