I just joined a maintenance project. For every new people joining the project, the client immediately asks the firstname and lastname of the newcomer and ask them as relation on LinkedIn. He said that he likes knowing who works with him. The others developers on the project didn't mind and accepted the invitation.

I don't want to accept the relation (and it is its right) but don't know how to tell the client.

Do you have any advice on how I could politely decline the LinkedIn invitation? I feel like we owe a polite explanation.

> Sorry Mr XXX, but I keep my LinkedIn contact for work relation

The sentence seems bad as we are somehow work related.

Is it better to accept the invitation then delete it discretely some days after?
