I would say no for various reasons.
1. It's a hassle to get 40 construction on each account and creating a tip jar (If you use one account then you're just making it easier for jagex).
2. It can still be traced. Mods can see how much someone put in the jar.
3. Only players who use tip jars are the ones who host houses; These guys make a few million at most per day and their house is always filled. Having an empty house with x5 the money in a tip jar than a normal host has is suspicious, especially if done regularly.
4. Construction is members only - which discourages non-members (especially bots) to trade.
