Yes, that is true.. I had noticed it in the past when I was yet thinking of getting my own PTC site..
Buxhost doesn't support bots btw.. Also a good way to check is to see how many refs are available
for rent at a time... for example ruicarlov recently rented 1000 refs at PTCSolution.. if the next day
he checks again and sees that there are still 1000 refs available to rent then something stinks..
Etc at the moment the site has 154690 members.
We can check back tomorrow to see how many more it will get.
Keep in mind that out of 154690 members more than just one members rent referrals regularly...
If there are usually no referrals to rent in big packs then things are a bit better.. calculating the odds.
However since usernames are masked we can never really know what's happening with rented refs
plus we can never really know how many members a site actually has..
The grids I am using are giving me a good view of each site's activity regardless of the stats they show on their homepage..
I've been thinking of creating a whole grid advertising guide based on these stats.. that could help me attract some advertisers
and have them join in my downlines, raising my earnings through purchase commissions instead of just clicking activity..
