Letter of Demand No. 019/SOMASI/RW/VIII/2026: Kadek Surya Mahardika (English Edition)

This post summarises Somasi No. 019/SOMASI/RW/VIII/2026, a formal legal notice I sent on 29 August 2026 to Mr. Kadek Surya Mahardika, holder of the X account @kadeksuryam, who works in Erkelenz, Germany. The letter was issued in Indonesian with English and German translations. It is a demand letter, not a police report, court filing or finding. He has not responded here, and I do not assert that he is guilty of any offence.

What the letter is about

Mr. Mahardika is an Indonesian citizen and, like me, an alumnus of the Bandung Institute of Technology (ITB). Copies went to the ITB alumni association (IA-ITB) and to his employer, IT-Bauschmiede GmbH in Erkelenz, because his professional identity as a software engineer is attached to his account.

My letter describes three items from @kadeksuryam:

1. 10 October 2023. A tweet with a Morse-code image and a screenshot of my private Instagram story, captioned (in my English rendering) "This is Morse code, which translates to 'my life is far more together than yours.'" On 6 November 2023 he re-quoted it in a thread with another account where someone wrote "we got into his story." In my reading, that shows a joint effort to access and mock my private content (about 168 views).
2. 9 November 2023. A quote of an "assessment card" that contained an explicit sexual accusation against me and a demeaning label, with his comment that it "just makes the reputation of 'wibu' [anime fans] even worse" (about 201 views). In my reading, this spread and reinforced an untrue sexual accusation.
3. About 10 May 2026. A re-post of a post by the campaign account "Kawal Rahmat Wibowo" alleging that I "frequently take photos of women without permission" and engage in "framing." The re-posted post recorded about 139,000 views and over 650 reposts.

I describe the 2023 conduct as part of a coordinated attack by dozens of classmates, marked by the "we got into his story" remark, and the two periods as repetition. I also say the account, with over 3,000 posts, has been one of the hotspots of online bullying against me. Those are my characterisations, and the letter does not name the other people.

Harm I described

Permanent reputational damage, an acute mental-health crisis including a bipolar disorder diagnosis, about 1.5 years of social isolation, lost professional networks and job opportunities, and roughly two years of recovery.

Legal basis I relied on

I wrote the letter myself, without a lawyer. For Indonesia it cites Art. 433(2) (written defamation) with Art. 441(1) and Art. 20 of the new Criminal Code, Art. 27A jo. Art. 45(4) of the 2024 ITE Law, and Civil Code Arts. 1365, 1366, 1372 and 1373, with joint and several liability alongside others. It says calumny (Art. 434 and Art. 45(6)) and electronic intimidation (Art. 29 and Art. 45B) warrant further investigation.

The cross-border angle: Indonesia and Germany

Because he lives in Germany, the letter also discusses German law: StGB §§ 185 (insult), 186 (defamation), 187 (calumny), 238 (stalking) and 194 (complaint requirement), and civil claims under BGB §§ 823 and 1004 including monetary compensation for serious violations of personality rights. I noted that Indonesia and Germany have no bilateral extradition treaty, and I described possible routes: extradition on reciprocity (Indonesian Law No. 1 of 1979 Art. 2(2); German IRG § 5), the point that Germany's bar on extraditing its own nationals does not apply to an Indonesian citizen, prosecution in Germany under StGB § 7(2) No. 2, mutual legal assistance, an Interpol notice, a direct complaint to the Mönchengladbach public prosecutor, and a civil suit in Indonesia or in Germany. I presented these as available mechanisms, not predictions.

What I demanded

By Tuesday, 1 September 2026, 17:00 WIB, I asked him to:

1. Remove all posts and screenshots that attack or accuse me, including the 2023 tweets and the May 2026 re-post, undo re-posts, and show proof;
2. Cease all cyber-attack, surveillance and dissemination of negative narratives, with a written undertaking;
3. Publish an open apology on his public account for at least 30 days;
4. Pay IDR 1,500,000,000 in non-pecuniary compensation, twice the IDR 750,000,000 maximum fine under Art. 45(6) of the 2024 ITE Law.

I offered coordination by email. If he did not comply, I stated I would file criminal reports in Indonesia, seek Interpol and legal-assistance channels, sue for an unlawful act, pursue parallel remedies in Germany, and publish the notice with its evidence.

Limits of this record

• This is my account and my legal reading; no court or authority has made a finding.
• Quotations are my English renderings of Indonesian originals captured in screenshots.
• The compensation figure is a demand, not an assessed loss.
• I am not a lawyer, and this post is not legal advice.

Right of reply and correction

Mr. Kadek Surya Mahardika is invited to respond, correct, or add context. A substantive reply may be published alongside this article, edited only for privacy, safety and relevance. If reliable evidence shows any statement here is wrong, I will correct it and note the change.

This letter also exists in a bilingual English and German edition: Letter of Demand No. 019 (English + Deutsch).
