Yeah I agree this looks like one of those times where the researches aren't interested in doing the stats at all so just mail it in.

Just ignoring the stats though the results seem pretty solid. 3x the number of citations with ~100 observations. If the tweets were truly randomly assigned and there aren't big outliers driving results (big ifs, not gonna go deep enough to find out), their conclusion should be fine.
