Unless you are using credit card then you should be careful

No issue with cash and reload pin as I withdraw every other day

be mindful of excessive withdrawals

if afraid, then dont do excessively .... do sparingly with low amount (ie dont be greedy)

remember to USE some of the $$ too. be a "good" user instead of being a withdrawal abuser

Yes this is the official statement
Yes, do not instant cash out, still unsure what the algorithm that trigger ban Go+ now

I been banned before, (straight no cc top-up), then lifted, and doing a monthly cash out and cash in cycle from ewallet (source from cc), so far, still can use CC to top-up to ewallet and transfer amount from ewallet to Go+
