You're right.
All this looks like blackmailing rather than "scamming OP".
Let's watch in this situation step by step:
OP bought 750 MONA coins one year ago. After 51 % attack on MONA network he became active again (through some period of time) and starts to claim for coins withdrawal . After he got rejected, he went to bestchange.ru and here and starts to blackmail exchange. Livecoin of course doesn't right to, because they blocked him (and most negative feedbacks from forum members because of that fact) and refered to some "user agreement".
Very suspicious situation as for me. Because of such things:
1. OP wants TO WITHDRAW coins. Not to refund them, not to sell or somethings. Mostly, ordinary people don't act in such ways. They want their money back, not "withdraw".
2. OP writes from a group of people
As long as there are people with the same opinion as yours, we will have exchanges, such as livecoin.
Really,
"we"?
"WE"? Who is that
"We"?
3. Interesting fact about one way to attack different exchanges:
Heдaвнo yзнaл пpo eщё oдин cпocoб кидaлoвa, нo в ocнoвнoм иcпoльзyeтcя для вopoвcтвa y биpж, a нe y oтдeльнo взятыx тpeйдepoв. Ho знaть пpo этoт cпocoб нyжнo, чтoбы нeнapoкoм нe влoшитьcя и нe пoтepять нa пocлeдcтвияx.
Кидaлoвo чepeз aтaкy 51%
Cyть cлeдyющaя: выбиpaeтcя кpиптa co cлaбым xэшpeйтoм или cпeциaльнo coздaётcя пoд этy зaдaчy шитфopк. Пpoвoдитcя aтaкa 51%, пepвoнaчaльнo cкpытнo, зaвoдятcя нa биpжy aтaкyeмыe мoнeты, пpoдaютcя зa твёpдый aктив c пocлeдyющим eгo вывoдoм. Дaлee пyбликyeтcя бoлee длиннaя цeпoчкa и oтмeняeтcя пepвoнaчaльный ввoд нa биpжy aтaкyeмыx мoнeт, т. e. идёт кидaлoвo биpжи - им пpoдaли вoздyx зa BTC.
Пocлe тaкoгo мoжeт yпacть кypc, в зaвиcимocти oт peзoнaнca. Кaк былo, нaпpимep, c Кaлcикoм нa Eбитe.

Taкжи oтключaют кoшeльки нa ввoд-вывoд пocлe фaктa (ИMXO мёpтвoмy пpипapoк).

Translation of selected part:
"The point: Cryptocurrency with weak hashrate is chosen (or creates) for such attack. Attack 51 % took place, covertly at first, compromised coins is sends to exchanger and sells for btc (or something valuable). Then scammer withdrawing btc and after that he publiches corrupted chain and compromised coins dissapear from exchanger history. In fact, scammer sold air to exchanger"One moment: to sell big amount of shitcoins you need at first increase trading volume and adjacent things. That means that some "clean" coins still stored on exchange (they were used for such things) and maybe scammer want them back too. In that case he will use earlier prepared accounts
with claims to open withdrawal.
Not excluded that we are witnesses of such scenario.
How on Earth is demanding to withdraw coins that you purchased, "blackmail?" This is like going into a store, purchasing a product, and then the store refuses to let you leave with the product that you just purchased. Is it blackmail if that customer then proceeds to write a scathing review on Yelp? I think not. If Livecoin does not want to allow withdrawals on Mona or Monero because they now have a fractional reserve due to the acts of malicious miners and vulnerability exploiters, then the right course of action is to suspend trading as well, until they can come up with a resolution to the issue. The right course of action is not to continue to allow people to trade the asset and profit off of it indefinitely. Furthermore, since both of these assets are trading much lower on their exchange, it is quite possible that Livecoin is buying the asset for a discount oin their own exchange and then selling the asset on another exchange for a huge profit. Due to Monero being a privacy coin, they could probably get away with this. I certainly hope that Livecoin is not resorting to such measures. However, they need to suspend trading, and come up with another resolution to solve their insolvency issue with both of these assets. Enough time has passed; so it is clear that neither the Mona team or the Monero team is going to cover their losses. It is high time that they explore the other option that they outline in their terms of service. Yes, making their clients take a haircut will piss some clients off; however, I am sure many will understand since in both cases, it does not appear to be an inside job. They can do what bitfinex did when they got hacked. They offered their customers a token, and devoted a small portion of their profits to distribute compensation to their clients who held or bought the token.
