I suggest not to post Telephone Numbers of 3. party
Just mention anyone wanting it to send you a PM and you reply in private
I would not like my phone number published ! Would you ???
Email Adress do the following, instead of " @ " write "at" or post it in a PM
Bots ( crawlers can not identify the "at" ) email adresses are collected by them and sold, that results in multiple Spam
Methinks, many are not aware of that
