If they indeed consulted a lawyer (the "thing" they posted as a "legal opinion" makes me doubt that), they now know their real legal situation, because the misleading things the paid lawyer wrote at their request and what the lawyer told them had to be completely different.

Let's summarized their legal mess:

I) They blocked my withdrawals 11 months ago, on December 2017:

Guilty.

II) They repeatedly refused to explain why, which means they had no legitimate reason to do that:

Guilty

III) They didn't inform me about the block and let me keep trading and even entrapping more money with a new deposit after the block.
This is fraud and a clear breach of their own TOS that demands them in case of a block to make “useful efforts by TRT to contact the User”(point 8.4: https://www.therocktrading.com/en/service_terms/3 ).
Guilty

IV) When I complained, they blackmailed me to send my documents or they would keep blocking my money against their previous assurances and FAQ that says "verification isn't mandatory" https://support.therocktrading.com/kb/faq.php?id=27
Guilty.

V) Since I argued this, they accepted I didn't have to send my documents, but they said that my money would be kept blocked "much more time". When I said I would take this public, they started demanding a copy of my documents again.

I have a copy of the CTO email of 21 August 2018 about this.
Guilty

VI) They wrote that if I don't comply they are going to keep my money "forever": https://bitcointalk.org/index.php?topic=4975753.msg47458158#msg47458158
Guilty

VII) They kept raising suspicions about my ownership ignoring all the evidence I have that no honest person can deny. Actually, they never even asked to check some of the evidence that they didn't see.
https://bitcointalk.org/index.php?topic=4975753.msg47458158#msg47458158
Guilty.

VIII) They kept lying about European Law, invoking european directives that they know aren't applicable (I told them so several times) because they only bind States members to adopt internal legislation:
https://bitcointalk.org/index.php?topic=4975753.msg47461136#msg47461136
Guilty.

IX) They kept lying about the meaning of their TOS, quoting several inapplicable rules and none in particular, just to confuse.
https://bitcointalk.org/index.php?topic=4975753.msg46183000#msg46183000
Guilty.

X) They posted a misleading paid "legal opinion" in order to confuse customers and the community that is illegal taking in account italian Legislative Decree No. 90 of 25 May 2017, article 3, n.º 5, i), under the name of "subjected entities", restricts ANY application of its provisions to a crypto exchange only to operations of conversion (not trading or exchange) of crypto to fiat that only happens when the customer makes a withdrawal:
https://bitcointalk.org/index.php?topic=4975753.msg47868314#msg47868314
https://bitcointalk.org/index.php?topic=4975753.msg47897379#msg47897379
Guilty.

XI) They created an alt account and used it to post defending themselves and paid members to post here to confuse the community:
https://bitcointalk.org/index.php?topic=4975753.msg45560191#msg45560191
https://bitcointalk.org/index.php?topic=4975753.msg46020217#msg46020217
Guilty.

They haven't deny ANY of my factual allegations, I'm not the one lying here. They actually confirmed the main ones: https://bitcointalk.org/index.php?topic=4975753.msg44951057#msg44951057
