Ezra, I believe Tablerock falls under Mike Trew's (northern mountain region CCC rep)area. You can send him an email voicing your complaint. All bolt and anchor replacement in North Carolina is done by volunteers who are supplied with bolts from the CCC and American Safe Climbing, it's unfortunately a long and arduous process to get to the thousands of rusties that need replacement throughout NC. Contacting the areas rep can speed up the process though.
Corey Winstead has been doing bolt replacement work up at table rock. As you can imagine, there are quite a few to get to. We ran out of hardware and are restocking, but CLimbtech is currently short on the legacy bolts that we prefer to use.
Also worth noting that we only just recently cleared the one for one replacement work with the forest service, that has been a sticking point at table for quite some time. As always, use your own best judgement on the quality of fixed anchors and you can always climb something else if you don’t like the look of the gear.
Ezra, I know what you mean - I thought about taking care of those a long time ago but those rust-welded 5-pieces can be an enormous pain to remove. Luckily they're (usually) much better than they look.
Give me a shout next time you're in the area. Hope all is well
