That bit about communions has got me. Up until learning that I had the general opinion that using features not intended to be there to your advantage was in some indefinable sense wrong. But I love being able to use a reverse communion. They make sense to me as an option with the communion spells.

Perhaps there's a difference in that they don't provide a risk-reducing advantage over the way they were intended to work.

VoD gets better every time it gets through a SC's defences without costing the caster any more gems, and it doesn't risk the caster to use it. Repeat casting isn't abusive per se, but the pair of bugs that this spell invokes generate a benefit way beyond the cost.

Cast and flee on BF enchantments gets you a top-notch effect, and the caster (who may well be empowered, loaded with boosters or holding artefacts) gets a minimal risk exposure. The risk/benefit ratio feels wrong.

Sending 40 slave collars costs perhaps a turn's worth of slaves in the late game, and a bit of investment in (frequently cheap) B1 forgers who can hunt when they're not forging. And you can keep on sending 10 collars a turn forever, just to keep the opponent topped up. Benefits are pretty big, if you ask me. The cost isn't huge as a late game trick. And there's no added risk to the producers of the items.

Twiceborn provides a greater than intended benefit, but in limited circumstances and the benefit is of limited utility. It's quite possibly a bigger benefit to use Twiceborn to avoid old age on an exceptional recruited mage or a Crone. I guess I'd probably call it abusive, though.

Communion working the way it currently does, though... Slaves casting at the same time as Masters clearly adds to the risk of fatigue death. Reverse Communion alters the benefit, and I'm not sure how much it increases it.
