simple symmetrical (i dunno what other word to use) link wheels can be easily identified by the spiders. i can't verify one way or the other if simple wheels are losing steam, but i've heard talk of it too. which might be jibberish being spit by random im failures, but does make sense. if the search engines wanted to combat manipulation of the serps, a simple wheel is easily identified. more complex wheels with crisscrossing paths however can be next to impossible to identify. i have a handful of different linkwheel charts which are apparently mathematically impossible problems to solve. the charts themselves are an np-complete problem, making them algorythmically next to impossible to solve. solving these problems still eludes computational scientists. and solving the problems grows harder and harder as the size of the problem grows. So if you're using a larger complex linkwheel, i imagine you're pretty safe for the time being. As for the simpler, easily identified linkwheels i really wouldn't be surprised fi they're taking a shitkicking, but i don't know i learnt linkwheeling from a hardcore mathfag. seems to be working fine for me...
