I'm a bit confused as to how much of a scam exchange Livecoin is...
I can only answer from my perspective.
As I said, already use them many years and never was in need to contact support. You are right and Livecoin is on the same level as Yobit, HitBtc, Nova, CoinExchange, (Cryptopia) or any other exchange like this mentioned. One just needs to know how to use them and read the TOS before registering. No red flags will save them if they don't do the homework in the first place.
This case against Livecoin is not an obvious case where a deposit is missing or withdrawal is not paid. This would be an obvious scam and only if repeated a couple of times.
Taking into consideration how many clients they have, support issues will happen and this is something which could be expected on every exchange, even the best one.
All exchanges have such Terms of Service. Better or worse, they are hidden between complex industry specificities, to mislead users or put there in the hope, that they will not understand it completely or never read it in the first place. Livecoin TOS are there from the very beginning and to bring them now, to the light is like a fall start in the sport. A very long one, because took a few years to find it, which proves that indeed nobody reads these rules before registering.
I don't see any other scammed members in this accusation thread against Livecoin, which is very rare and weird. Taking into consideration, how many people are scammed because of exchanges.
We can assume, that this accusation thread caught attention from the entire forum and all interested members have already seen it, so why are they not complaining also?
Despite, how shady and not moral this TOS are for many DT1, they are there from the beginning and one has, to agree with them after reading. I have read these terms and there is nothing more as an exception to close an account when one will spread support information or any other false information against the exchange. Not so hard to do it if you know about it. To accuse now Livecoin, that they use it against OP is not appropriate, because OP was warned multiple times, proven to be lying about the exchange and even admit it publicly.
Livecoin exchange is the high-risk crypto exchange but is not a scam so far. No more or less, like any other even more reputable exchange.
