From a cursory glance at their BPIP pages I can see:

• @AdkinsBET has received merit from all five of these alts.
• The last UID to receive merit from this cluster is @mikelsmith2020 (four of the five send this UID merit)
• sempak both sends and receives merit from both wildan88 and gadado
• Plus,  yayayo gives wildan88 merit who then gives sempak merit who then on sends merit to gadado

Conclusion:

Merit abuse by these five alts.
