We evaluated 261 Disk Detective objects of interest with imaging with the Robo-AO adaptive optics instrument on the 1.5m telescope at Palomar Observatory and with RetroCam on the 2.5m du Pont Telescope at Las Campanas Observatory to search for background objects at 0.15"-12" separations from each target. Our analysis of these data leads us to reject 7% of targets. Combining this result with statistics from our online image classification efforts implies that at most 7.9%+/-0.2% of AllWISE-selected infrared excesses are good disk candidates. Applying our false-positive rates to other surveys, we find that the infrared excess searches of McDonald+ (2012, J/MNRAS/427/343 and 2017, J/MNRAS/471/770) and Marton+ (2016, J/MNRAS/458/3479) all have false-positive rates >70%. Moreover, we find that all 13 disk candidates in Theissen & West (2014, J/ApJ/794/146) with W4 signal-to-noise ratio >3 are false positives. We present 244 disk candidates that have survived vetting by follow-up imaging. Of these, 213 are newly identified disk systems. Twelve of these are candidate members of comoving pairs based on Gaia astrometry, supporting the hypothesis that warm dust is associated with binary systems. We also note the discovery of 22{mu}m excess around two known members of the Scorpius-Centaurus association, and we identify known disk host WISEAJ164540.79-310226.6 as a likely Sco-Cen member. Thirty of these disk candidates are closer than ~125pc (including 26 debris disks), making them good targets for both direct-imaging exoplanet searches.2018ApJ...868...43Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/868/43CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)II/332 : c2d Spitzer final data release (DR4) (Evans+, 2003)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/337 : Gaia DR1 (Gaia Collaboration, 2016)J/ApJS/101/117 : UBVRIJHKLMNQ photometry in Taurus-Auriga (Kenyon+ 1995)J/MNRAS/313/43 : OB association members in ACT+TRC Cat.
