Top Associated Accounts
The network is small, coherent, and climbing-centered. The strongest connection is the coaching/training relationship with @ant0_pwr, followed by repeated gym and venue anchors in Paris. This looks like a real hobby and community graph, not an artificial engagement ring.

Best next moves
Verify whether @lucculnus is the same Luc Sun as the LinkedIn candidate
This is the main unresolved identity pivot. A match would strengthen attribution, while a mismatch would narrow the subject quickly.
Audit audience quality on @lucculnus
Follower count is small and the current dataset does not show follower quality. A quick sample can confirm whether the audience is mostly real or noisy.
Monitor @lucculnus for any new bio link or promotional move
The profile currently looks personal. A new external link or paid promotion would be the clearest reason to reassess credibility.
Review repeated association with @ant0_pwr
This is the strongest network signal in the current evidence and likely explains the training content and performance captions.

Identified Risks
3⤷ 3 additional risks found in this analysis
Identity resolution
LikelyThe account is well attributed, but the bio anchor "⚓ 2027" is still ambiguous and not fully explained.
Audience authenticity
Roughly even chanceFollower quality and bot presence cannot be fully validated from the supplied evidence, so audience trust remains only partially assessed.
Impersonation risk
UnlikelyLow but not zero. Any public account with a real name can be copied or spoofed, even when the current evidence looks genuine.

Recommendations

Confirm identity through additional public cross-checks
3 stepsUse a few more public pivots to see whether @lucculnus belongs to the same Luc Sun seen elsewhere online.
Check audience quality before trust decisions
3 stepsTreat the current follower count as only a rough signal. It is too small to prove legitimacy or fraud on its own.
Watch for commercial transition
3 stepsThe profile currently looks like a personal climbing account, but that could change if it starts promoting products or coaching services.
