No, not at all. Being cautious about giving your phone number to a complete stranger is entirely reasonable.
On the other hand, posting messages publicly casting suspicion on another member of this forum SOLELY on the basis of the length of time that person has been an official member, such as:
Now, how do I get past the suspicious thoughts that the poster of this thread has been here less than a month?
and such things as publicly discounting my opinion, which others have done in other threads - simply because I'm relatively new here would definitely fit into the category of paranoia, and sometimes worse.
But, it seems (as someone who has recently joined this esteemed forum) that at least some of the people here have their established "clique" and don't really give a flip about being welcoming to newbies.
And some are just... a bit paranoid. Or cautious. Well, I can understand that part. After all, most of us (myself included) don't broadcast our full names here, just "monikers" like "Nita Nupress" and "butter pecan fan".
But it's no excuse for abusing recent arrivals.
Toughen up!
