Sure, but with those tattoos, the 14 & 88 are significant and inescapable. There’s no ambiguity and their presence is not hidden. But once you’re counting the number of words in a tweet, you’re talking about things much more hidden. It doesn’t work well as a dog whistle if the metaphorical dogs can’t hear it, either.
Plenty of ambiguity there. I think you may need to evaluate what your motivation is to need to keep disbelieving that racist dogwhistles can actually be ambiguous, especially considering they are that way by design.
Well, along the lines of counting the number of words in a tweet, maybe 14 stars? And then chains, where the linked chains look kinda like 8s? Something where the 14 and 88 are present, but not obvious unless you think to look for them.
That is an mechanism which insulates even well-documented conspiracies that use numerical symbols as identification banners, which is probably why certain of them do exactly that.
