I think people might be a bit too quick to ban Gothitelle, or are at least overestimating the usefulness of Shadow Tag. Just going off of theorymon right now, trapping in UU is a lot harder that it seems, especially with Gothitelle's poor Speed, mediocre typing, and weaknesses to all three hazards. The fact of the matter is that Gothitelle cannot just switch in on a Pokemon, Calm Mind up to +6, and sweep a team since it has limited (but not bad) bulk and few resistances to abuse.
Furthermore, it's obvious that if Gothitelle wants to set up, it's going to have to do so against a defensive Pokemon (good luck setting up on Raikou, Zapdos, etc.), and Gothitelle has some problems dealing with some of the defensive Pokemon in UU.
Roserade outspeeds Gothitelle and either Sleeps it or Sludge Bombs it. If Gothitelle falls asleep, then it's useless. If Roserade is the defensive variant, then Gothitelle could easily succumb to Poison and die to a combination of Giga Drain and Sludge Bomb. It is possible that Roserade can adapt to Gothitelle by running some Special Attack EVs on both sets. Bronzong loses to Gothitelle, however. Maybe Shed Shell will become usable on Zong?
Blastoise can always Roar Gothitelle out, so Gothitelle will not be able to set up or anything. Hitmontop can Toxic the Goth tower, but will ultimately lose to her. Snorlax wrecks Gothitelle of course, and Swampert does decent damage with Earthquake. Swampert can also set up Rocks and Roar Gothitelle out since I doubt he takes too much damage from Psychic.
Slowbro loses to Gothitelle, but Scald probably does decent damage. Since Slowbro already has Regenerator there's no reason why it can't run Shed Shell to get away from Shadow Tag anywat, right? Slowbro has plenty of recovery in Regenerator and Slack Off already.
Porygon2 versus Gothitelle is interesting. On one hand, Porygon2 probably loses to CM Gothy, but Gothy needs significant boosts to outstall Porygon2. It'll be interesting to see how the metagame adapts.
Claydol gets wrecked by Gothitelle I believe, at least by the SubCM one. Maybe this will convince people to stop using Claydol.
Umbreon probably hits it hard with Payback, so that will make Umbreon an even better Pokemon in UU. Milotic loses one-on-one, however. I always thought Milotic was overrated anyway, but other Pokemon can take Milo's spot.
Sableye lols at Gothitelle, and Suicune can boost alongside it and possibly phaze with Roar. Maybe RoarCune will rise in usage?
Gligar will lose to Gothitelle unless it starts running U-Turn or enough Speed to Toxic it before Gothy Subs. So GLigar can easily adapt by running a little more Speed. Registeel can beat Gothitelle one on one too.
Though this is pretty cursory analysis of Gothitelle, it seems to me that UU can definitely adapt to Gothitelle's presence, even if a few Pokemon fall out of favor (This is normal. Just because Milotic won't stay as good as it "should" be doesn't mean that Gothitelle is broken). Plenty of defensive Pokemon have ways to give Gothitelle a hard time, be it phazing, setting up alongside it, using U-Turn, or even having to resort to Shed Shell.
Speaking of Shed Shell, there's no reason why a few defensive Pokemon such as Slowbro can't run Shed Shell over Leftovers if they don't want to be setup bait for Gothitelle. Just because Shed Shell becomes viable over Leftovers doesn't mean that Gothitelle is broken. In fact, if more Pokemon use Shed Shell, that makes Shed Shell more viable. I believe that's called metagame diversity, which is a positive thing.
I know nobody's immediately alleging that Gothitelle is broken, I'm just trying to anticipate some of the arguments that pro-ban folks might use. I am not sure at the moment whether Gothitelle is broken or not; I doubt anyone can know for sure. But my first impulse is that Gothitelle will not be broken, and I want a full test period to test Gothitelle out. It'll be interesting to see how the metagame adapts to the new trapper in town, and a quick-suspect will deprive the UU community of a thorough testing period.
Should Gothitelle be suspected? Probably in the future, but putting Gothitelle on the chopping block as soon as it enters the metagame is a mistake. So I would not like a quick suspecting.
I'd also like to respond to one of the more pro-insta-suspect posts above mine.

but SubCM is too dangerous to be given a pass, imo. What's to stop it from coming in on something like Blastoise or Slowbro and getting to +6 with a Sub? It's not utterly broken, but it's worth a fast suspect vote if nothing else.
SubCM won't be its best set in my opinion, since it's dealt with very easily. If you look at the walls in UU, a lot of them have ways around SubCM Gothitelle be it U-Turn, Seismic Toss, Toxic, or Shed Shell in the most extreme cases.
