The calculations of the Bhabha Suppression Effect (BHSE) in luminosity measurement at the International Linear Collider (ILC) were revisited. Preliminary estimates of the BHSE at the Compact Linear Collider (CLIC) were performed for the first time, as well. The regularities in the largest contribution to the BHSE, the Beamstrahlung, are used to find event selection algorithms that minimize the BHSE at ILC, or reduce the sensitivity of the BHSE on the variations in the beam parameters. At CLIC, the BHSE is much larger, so that the precision of the luminosity measurements critically depends on the precise estimate of the BHSE.
