  Recently, several astrophysical data or would-be signals has been observed in
different dark-matter oriented experiments. In each case, one could fit the
data at the price of specific nature of the coupling between the Standard Model
(SM) particles and a light Dark Matter candidate: hadrophobic (INTEGRAL,
PAMELA) or leptophobic (WMAP Haze, dijet anomalies of CDF, FERMI Galactic
Center observation). In this work, we show that when one takes into account the
more recent LEP and Tevatron analysis, a light thermal fermionic Dark Matte
(\lesssim 10 GeV) that couples to electrons is mainly ruled out if one combines
the analysis with WMAP constraints. We also study the special case of scalar
dark matter, using a mono-photon events simulation to constrain the coupling of
dark matter to electron.
