There is an interesting analysis by the European Media Observatory on the Romanian election – (Archived link).

On ‘TikTok’s role in Romanian politics’ and the ‘Candidate Performance Metrics’, it says, among others:

• Călin Georgescu: Notably surged in popularity, garnering 120 million views, particularly in the final two months. This increase was attributed to coordinated campaigns that used both direct promotion and indirect influence via unpaid influencers, often lacking appropriate labeling. A salient example is the #echilibrușiverticalitate campaign, which reached 2.4 million views through these tactics.

The analysis also says:

The lack of effective moderation allowed for widespread dissemination of unverified information, particularly affecting extreme-right candidates.

Concerns around unlabelled or undeclared political content in the 2024 Romanian presidential elections, particularly on TikTok are significant. They emphasize a lack of transparency in political campaigns, notably involving candidates like Călin Georgescu, who used the platform without disclosing the funding and motivations behind their promotion. The employment of influencers without adequate disclosure raises ethical issues complicates voters’ understanding of the content.

The notable gap between projected poll figures (around 10%) and actual results (over 22%) raises concerns about potential external influences, including foreign interference.
