  Short-orbit gas giant planet formation/evolution mechanisms are still not
well understood. One promising pathway to discriminate between mechanisms is to
constrain the occurrence rate of these peculiar exoplanets at the earliest
stage of the system's life. However, a major limitation when studying newly
born stars is stellar activity. This cocktail of phenomena triggered by fast
rotation, strong magnetic fields and complex internal dynamics, especially
present in very young stars, compromises our ability to detect exoplanets. In
this paper, we investigated the limitations of such detections in the context
of already acquired data solely using radial velocity data acquired with a
non-stabilised spectrograph. We employed two strategies: Doppler Imaging and
Gaussian Processes and could confidently detect Hot Jupiters with
semi-amplitude of 100 $m.s^{-1}$ buried in the stellar activity. We also showed
the advantages of the Gaussian Process approach in this case. This study serves
as a proof of concept to identify potential candidates for follow-up
observations or even discover such planets in legacy datasets available to the
community.
