I always block them and report spam, only the greedy and newbie fall for their tricks they imitate the main admin's name to perpetrate fraudulent act. Never respond to any suspicious help in PM.
Many scammers in telegram it is given that they really do exists so our part is never trust those people. I have experience this kind of scam in telegram convincing to transfer funds on the project that they promote. So thats true never trust and better block those scammer.
The famous tactic is impersonation and they talk with you as a "team member" and actually forget to add the "kindness". Scammers know how to scam other people and they become more professional after each failed scam attempt. Blocking these accounts is the one-way street and they will come with a new nickname for taking more from you. Only taking money from the victims calm them down, so everyone has to do their own diligence. Similar names can not be observed from first look, there is always more behind the scam accounts.
