The threshold question of "many people" (around 30) or "a wide public" (around 150) is the central defence lever for juvenile defendants. Which platform constellations correspond to which threshold is, in advisory practice, surprisingly often unclear, and that is precisely where defence strategies come in.
WhatsApp, Signal, Telegram groups, closed. Closed groups under around 30 members regularly do not reach the threshold "many people" under Section 283 para. 1 StGB, according to settled case law and academic writing. Subsidiary offences are then to be examined: Section 107c StGB (threshold "a larger number of persons", in practice about 10, see the previous article), Section 115 StGB (private prosecution from 3 persons). Groups with around 30 to 149 members, typical upper-school class chats, sports club groups, year-group chats, can fulfil Section 283 para. 1 StGB, but not yet para. 2 (a wide public). Groups with around 150 or more members, public Telegram channels, Discord servers of larger reach, can fulfil paras. 1 and 2.
TikTok, Instagram, Snapchat, stories and posts. With a public profile, the reach is not factually limited, Section 283 para. 2 StGB is regularly fulfilled as soon as the post actually achieves a reach of around 150 or more. With a private profile with limited follower count, para. 1 is possible, para. 2 only where the threshold is actually exceeded. Stories and reels with time-limited visibility (24 hours for stories) change the calculation of the offence period, relevant for the continuing-offence argument.
Stitches, re-posts, viral reach ex post. A particular constellation: an original post is re-posted, stitched, or picked up as a meme by third parties on a mass scale, the reach explodes ex post. From a defence perspective, what matters now is the intent horizon at the time of the offence: the defendant could only reconcile themselves to what was foreseeable at the time of their own post. A viral reach explosion later triggered by third parties cannot, without more, be attributed to the defendant as conditional intent regarding Section 283 para. 2, the subsumption regularly remains at para. 1.
Anonymous accounts. Platforms are obliged under the KoPl-G and, since 17 February 2024, under the DSA Accompanying Act (BGBl. I 182/2023) to disclose the user data of anonymous posters on a court order. Anonymity does not protect, anyone who thinks an anonymous account protects them from prosecution is mistaken. The defence lever lies not in the supposed anonymity itself, but in the chain of evidence: multiple persons on the same end device or WLAN connection? Account assignment via email or telephone number unambiguous, or manipulable via recovery routes? Has the prosecution secured, alongside the IP, also the device identification?
Private conversation versus small group. A direct message between two persons is a private conversation, Section 283 StGB not applicable. Small groups under 10 persons fulfil neither Section 283 nor, as a rule, Section 107c StGB; at most Section 115 StGB remains as a private prosecution offence. Small to mid-sized groups of 10 to 29 persons can fulfil Section 107c StGB, not Section 283. Mid-sized groups of 30 to 149 open up Section 283 para. 1; from around 150 also para. 2.
